[sage-support] Re: radius of convergence and inequalities
Hi Jason, Qepcad sounds VERY interesting. I have not heard about it before. Do you know how to install qepcad (on a mac)? I did not find it in the optional packages list.

[sage-support] Re: radius of convergence and inequalities
I just had another look around for qepcad on sage. Here is what I found: There is a ticket for including an interface to qepcad (http:// trac.sagemath.org/sage_trac/ticket/772), which has been merged in sage 3.1.2.alpha2. According to this ticket, it seems that qepcad does not compile properly on osx. Is this the latest stand on this?

Sorry, meanwhile I found that I was mistaken about __del__ versus __dealloc__: There is no __del__ method for extension types. My conjecture was that the memory leak was caused by (one of) the two extension types in my code. But now it seems that the problem is located somewhere else. At http://sage.math.washington.edu/home/SimonKing/f5/f5.pyx is the version with extension classes, and at http://sage.math.washington.edu/home/SimonKing/f5/f5B.pyx is essentially the same code with Python classes replacing the extension types. The memory leak is still present with Python classes. So, it seems to me that the leak might come from other compiled components. Libsingular? This is what I'm using most frequently. Valgrinding revealed a definite loss of 612 bytes and a potential loss of 394,644 bytes in two runs.

[sage-support] Re: radius of convergence and inequalities
Thanks, but the comments on the install page do not sound too promising. Even if I finally managed to get qepad to work on my computer on its own, I wouldn't know how to make sage work with it, so I'll wait until someone more knowledgeable with osx and enough time solves the problem. Or until Sage itself will be able to do what qepad does. :) By the way, I haven't found a way in Mathematica to solve inequalities, so this would definitely be great. Thanks for your help!

Mathematica implements the same sort of basic ideas that qepcad implements, I think.

If you could get qepcad to compile on OSX (just by itself), I think we could get what you did to work in Sage. To get the QEPCAD sources that Sage uses, download the spkg, then in a terminal do: tar -xjvf qepcad-1.50.spkg Then the sources should be in the qepcad-1.50/src/ directory.

Yes, that's right, Mathematica does solve inequalities using the Reduce[] command. Forgot about that! If EQPCAD does what Reduce[] does in Mathematica it may be well worth the effort to get it installed. Thanks for the instructions. I may give it a try. I can't wait for the improved equation and inequality solver in Sage. Good luck to Carl Witty!

I get the following error messages:

Actually, the qepcad distro is only made for Linux and Solaris, so I suppose we would need to put more effort into getting it compiled on a mac. mksysdep.pl only tries to get the architecture of the computer in order to call the appropriate install script, but there is no install script for a Mac, anyway. I saw that there are people that got it compiled on a mac, but only the older version of qepcad (e.g. http://www.cl.cam.ac.uk/~lp15/papers/Arith/qepcad-for-mac.html).

Sorry! > No problem. Thanks for looking into this. Again, the first step here is to get it compiling on a mac. I don't have a mac, so I can't test this, but you are welcome to try. The link you provide above gives a bzipped tar file that contains several patches to get qepcad to compile on a mac. The version they use is actually fairly close to the version we use. There were a couple of bug fixes and some work to get qepcad to work on 64-bit systems. The main change between 1.48 and 1.50, I believe, was the license change that was needed to incorporate qepcad into Sage. Can you compile the package at the link you gave above? If so, it looks like the work may have already been done for us and it's just a matter of including that Mac OSX patch.

The tbz archive has a README, which is a script that apparently compiles the package, though. So downloading the package at the link you gave, untarring it, and doing sh README seems like it should work. You might have the change the first statement in the README. side note: Interestingly, the README is a shell script. So apparently, in this case, the code has become the documentation!

[sage-support] Re: solve, integrate, series
Dear William, thanks for your quick answer, even though it doesn't make me too happy. I'm having a hard time here, I must admit. So far I thought that sage would do most things out of the box, and it's only inconsistent (eg., arguments to plot, plot3d and integrate vary wildly. There are several functions plot, plot3d, contour_plot, parametric_plot, etc. and not only one that decides on the type of self what to do. limit requires "x=x0" as second argument, and not "x==x0" as would be natural for an equation. The syntax for lambda is completely different to usual function definition - no parens for example. sage just eats all cpu time when I call contour_plot with an equation as self by mistake. In general, it seems that functions are "dangerous", i.e., do little to no type checking, but it's not at all clear when a method does the same thing as the function, and when it is available at all (eg. contour_plot is not a method, while plot is.) A general rule would be extremely helpful here. Sorry for the rant.

I don't see the problem in having more than one function name for plotting.
Actually I think I agree with you about one (easily fixed) problem, since
the various plot functions might be hard to find. It would be nice for
all plotting
functions to start with plot (eg, plot_parametric could be an alias for
parametric_plot), so the variations can be found by tab completion.

David Harvey implemented something for 1st order linear DEs of the form
y'=ay+b:
sage: R. = PowerSeriesRing(QQ, default_prec=10)
sage: a = 2 - 3*t + 4*t^2 + O(t^10)
sage: b = 3 - 4*t^2 + O(t^7)
sage: a.solve_linear_de(prec=5, b=b, f0=3/5)
3/5 + 21/5*t + 33/10*t^2 - 38/15*t^3 + 11/24*t^4 + O(t^5)

Yes, in the 1st or 2nd order linear cases, but the methods call Maxima:
sage: x = var('x')
sage: y = function('y', x)
sage: desolve(diff(y,x) + y - 1, y)
e^(-x)*(e^x + c)
sage: f = desolve(diff(y,x) + y - 1, y, ics=[10,2]); f
e^(-x)*(e^x + e^10)
sage: plot(f)
See calculus/desolvers for more details/examples. Hats off to
Robert Bradshaw for this.

[sage-support] How remove these jsMath messages when print Sage notebooks?
When I print a Sage notebook to a PDF file, I see the following text in a red box at the top that I'd like to remove... " To print higher-resolution math symbols, click the Hi-Res Fonts for Printing button on the jsMath control panel." Also, When I press the "print" link on a Sage web notebook I get the following error message in an popup box... "It looks like jsMath failed to set up properly (error code -7). I will try to keep going, but it could get ugly." How fix/remove these?

I think that getting message is a bug. I remember when we didn't have to install the fonts. I got sick of it and finally installed the fonts this morning.

Well, the problem is namespace pollution. Already now, if I hit tab after x, I
get roughly 100 possible completions. In a strongly typed environment, this is
unnecessary. I do not see any benefit in having more than one name to do one
thing. Of course, if the argument types are the same you will probably need to
have several functions.

Oh no, more namespace pollution :-)

Ah, great. That's exactly what I was looking for (except, why is it called
desolve and not solve, so I can find it...?) And why is it a function?

[sage-support] Using Sage on Windows
Hi, all,
I am helping someone who has a Windows system, and wants to use Sage.
She has the VMWare gizmo set up and working fine. I have a silly
problem, due to my long history of Windows Rejection: I have a file
on Windows that I want to "attach" in the Sage notebook. Can that be
done? The obvious doesn't work ("/home/user/D:/Documents/..." not
found).
Suggestions? Pointers?
Thanks, as always.

It's possible but you have to set up some sort of sharing
between Windows and VMware. I.e., the Windows filesystem
(or some subset of it) has to be made available to vmware.
This is I think very easy in VMware Workstation via menus. I don't know
if it is easy or not in VMware player. I don't actually have access
to a windows machine right now, so i can't give step-by-step
directions. I hope somebody else can promptly respond to
this email who can.

I'll poke at VMWare when I see her next. If anyone has some good
ideas, I'd love to hear `em.

Can't you upload the file as a "data file" and then attach it from
there? That way everything is done from the notebook.

I wasn't sure that would work. It was not clear to me where the
upload/download commands were operating. I will give that a shot.
To make sure I know what's going on here, the file to be attached is
currently sitting in the Windows file system, and needs to be in the
VMWare/Linux file system, correct?

I believe that it will be uploaded/downloaded to the $DATA directory, so
it could be attached with:
attach $DATA/filename.sage
I haven't tried, it, though.

[sage-support] Bug in GP conversion?
Hi, I've got a (truncated) matrix over a power series ring over a finite field that I want to convert to a GP matrix so that I can take its kernel. Since the matrix is truncated, it can be viewed as just being over a univariate polynomial ring. I want to take its kernel, but the echelon form over a univariate polynomial ring over a finite field is not yet implemented. I knew GP can do this, so I was going to send the matrix to GP and have GP compute the kernel. But if I send the matrix as a matrix over the power series ring, the coefficients are not sent as being over a finite field. On the other hand, if I redefine the matrix over the polynomial ring, the coefficients are treated as being over a finite field. I could reconstruct all of my matrices as being over the polynomial ring once I truncate my series, but that seems like a silly hack -- GP understands power series rings over a finite field, so the conversion shouldn't be a problem. I'm running SAGE v3.0.2. Thanks, Salman Here is the code and output: sage: R.=PowerSeriesRing(GF(5),"x") sage: m=matrix(R,2,[2+x, 1+x, 2+3*x,1+2*x]) sage: m.kernel() --- NotImplementedError Traceback (most recent call last) /Users/salmanhb/Documents/work/research/computations/sage/ in () /Users/salmanhb/Documents/work/research/computations/sage/matrix2.pyx in sage.matrix.matrix2.Matrix.left_kernel (sage/matrix/matrix2.c:7985) () /Users/salmanhb/Documents/work/research/computations/sage/matrix2.pyx in sage.matrix.matrix2.Matrix.echelon_form (sage/matrix/matrix2.c: 15292)() /Users/salmanhb/Documents/work/research/computations/sage/matrix2.pyx in sage.matrix.matrix2.Matrix.echelonize (sage/matrix/matrix2.c:15092) () /Users/salmanhb/Documents/work/research/computations/sage/matrix2.pyx in sage.matrix.matrix2.Matrix._echelonize_ring (sage/matrix/matrix2.c: 14807)() NotImplementedError: echelon form over Power Series Ring in x over Finite Field of size 5 not yet implemented sage: gp(m) [x + 2, x + 1; 3*x + 2, 2*x + 1] sage: R.=PolynomialRing(GF(5),"x") sage: m=matrix(R,2,[2+x, 1+x, 2+3*x,1+2*x]) sage: m.kernel() --- NotImplementedError Traceback (most recent call last) /Users/salmanhb/Documents/work/research/computations/sage/ in () /Users/salmanhb/Documents/work/research/computations/sage/matrix2.pyx in sage.matrix.matrix2.Matrix.left_kernel (sage/matrix/matrix2.c:7985) () /Users/salmanhb/Documents/work/research/computations/sage/matrix2.pyx in sage.matrix.matrix2.Matrix.echelon_form (sage/matrix/matrix2.c: 15292)() /Users/salmanhb/Documents/work/research/computations/sage/matrix2.pyx in sage.matrix.matrix2.Matrix.echelonize (sage/matrix/matrix2.c:15092) () /Users/salmanhb/Documents/work/research/computations/sage/matrix2.pyx in sage.matrix.matrix2.Matrix._echelonize_ring (sage/matrix/matrix2.c: 14807)() NotImplementedError: echelon form over Univariate Polynomial Ring in x over Finite Field of size 5 not yet implemented sage: gp(m) [Mod(1, 5)*x + Mod(2, 5), Mod(1, 5)*x + Mod(1, 5); Mod(3, 5)*x + Mod(2, 5), Mod(2, 5)*x + Mod(1, 5)] --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---
[sage-support] Porting Sage to AIX
Hi, I am trying to port sage 3.1.1 to an IBM Power5 AIX system. After I install gap (in 32 bits), I get: > ./sage -- | SAGE Version 3.1.1, Release Date: 2008-08-17 | | Type notebook() for the GUI, and license() for information.| -- Timeout exceeded in read_nonblocking(). version: 2.0 ($Revision: 1.151 $) command: /site/PET/src/build/sage-3.1.1/local/bin/gap args: ['/site/PET/src/build/sage-3.1.1/local/bin/gap', '-b', '-p', '- T', '-o', 'G', '/site/PET/src/build/sage-3.1.1/data//extcode/gap/ sage.g'] patterns: gap> buffer (last 100 chars): before (last 100 chars): after: match: None match_index: None exitstatus: None flag_eof: 0 pid: 360896 child_fd: 13 timeout: 30 delimiter: logfile: None maxread: 10 searchwindowsize: None delaybeforesend: 0 I downloaded gap 4.4.10.p8.

[sage-support] Re: Porting Sage to AIX
Hi, I have tried building gap in both 32 bit and 64 bits. With 32 bits I had to add a -Os optimize for size option so it would not exceed the memory limits.

I'll poke at VMWare when I see her next. If anyone has some good
ideas, I'd love to hear `em.

You can upload a file just like an image into a given worksheet,
and it appears in the data directory. Then I think you can do
attach filename.sage
(without the $DATA). I'm pretty sure that works in
recent versions of Sage.
