[sage-support] axes label in plot3d
There is an older post about this issue: http://groups.google.com/group/sage-support/browse_thread/thread/ecdf6f75295ad76d however the "reply" button is missing there (only "reply to author" is available). There are some "problems" in using text3d as a solution of adding axes labels to a 3d plot: 1) text3d does not seem to aware of latex input (while "text" does) 2) The labels added by text3d disappear if one use Tachyon to show the plot. I was hoping to get around these by looking at the code for text3d. Hum.. I can locate text.py but somehow couldn't find text3d.py (maybe it's provided by a file with a different name).

[sage-support] Using HTML and plot function
Hi all!
How to use both html and graphics?
for example insert plot(sin,0,4) in html-tabe?
i am trying:
html('sin(x):')
html(myimage)
html('')
but it gives table with text "sin: Graphics object consisting of 1
graphics primitive".. i'd like to see image, not text.
Thank you.

You have to pass those values in the substitution explicitly. You can achieve this by doing sage: abc.subs(locals()) 239.108910891089 BTW, I think this syntax is very confusing: sage: x_ulCal = x_ul(d=d,epsilon_s = epsilon_sMin) I suggest that you use .subs() directly, e.g., sage: x_ulCal = x_ul.subs(d=d,epsilon_s = epsilon_sMin) The method you use might be deprecated soon.

Well, bugs are fixed all the time, so a two months old version can be
quite outdated.

It blows up for me in 3.2.2, so this is a bug.

The is a libgcc_s.so.1 picked p from the binary G95 that Sage ships.

Nope, build a copy of Sage that doesn't use the binary G95, but the
system gfortran compiler. From README.txt:
NOTE: If you're using Fortran on a platform without g95 binaries
included
with Sage, e.g., Itanium, you must use a system-wide gfortran.
You
have to explicitly tell the build process about the fortran
compiler and library location. Do this by typing
export SAGE_FORTRAN=/exact/path/to/gfortran
export SAGE_FORTRAN_LIB=/path/to/fortran/libs/libgfortran.so
Deleting the G95 binary and rebuilding the spkgs which use Fortran
will also work, but that is a rather complicated thing to do unless
you know exactly what you are doing :)
Let us know if you run into any trouble.

[sage-support] Floatting point LLL Revisited
Dear Santanu, I am Santanu Sarkar,research fellow, from Indian Statistical Institute. I use SAGE in my research. Can you please tell me is there any function in SAGE by which I can reduce a lattice whose entries are floating point? Note that LLL algorithm can not be use in this case and "Floatting point LLL Revisited" by Phong Nguyen and Damien Stehlé can be use here. If you have any soure code for this purpose kindly send me. first the title "Floating point LLL Revisited" refers to the use of floating-point numbers *inside* the LLL algorithm, while the inputs are usually integers. Now if you have floating-point *inputs*, a simple trick is to convert them to integers, for example round(C*m[i,j]) where C is a large constant. If all your m[i,j] are of the same order of magnitude, and of the same precision, then C=2^k might even perform an exact conversion (don't forget to divide your reduced vectors by C at the end). Damien Stehlé (in cc) might add more details.
