I really don't see the point of being able to write matlab code from LyX; it seems much more efficient to do the other way round: create LyX or LaTeX code from matlab and import it with input. Working this way allows to update freely the input by running the math numeric interpreter. This technique allows also to import graphics and tables. The problem of math import from outside LyX is more intricated for three reasons: - the typography is complex; - the macroprogrammation which comes with TeX math mode: importing pieces of code forbids reuse of macrocommands; this is a minor point if the code import is efficient beacuse you don't care much about code duplication then; - as is, the math mode of (La)TeX is really different from the one produced by mathed because the latter does mot allow to reenter in text mode and then in math mode, even with ERT. So as things are now, Maple e.g. can export to (La)TeX, but going one step further towards LyX without any ERT in the result does not work (just run reLyX to check). Using macros helps in that translation, but LyX lacks currently a user defined math panel which would made tractable a big set of macros. Of course, as it has been said elsewhere in the thread, XML/LaTeX is an issue (there must be a workshop or a symposium about it next May). Regards -- Jean-Pierre

Compilation of Lyx 1.1.4
Hi, I'm running Lyx 1.0.1 on SUSE 6.2. Recently I wanted to upgrade to 1.1.4. But if I try to run "./configure" I get the following error. X-Libraries not found. If you work under Linux check wether you have the development-packages installed. Which development packages are meant by that and why does Lyx 1.0.1 run fine?

did you write the mathimatics expressions in mathomde, like this one
\fbox{$\frac{3}{7x}$}
on the other hand you can insert a math-formula with LyX:
\fbox{ math->formula }

Re: wild development ideas
The idea is implemented in Scientific Workplace (www.tcisoft.com) There it is possible to use Maple or Mathematica from a latex(2.09)-shell. Isn't is possible to use Mathematica from MS-word as well (Wolfram should have a addon for that??) Would indeed be nice to use Scilab or MuPAD or Maxima (whatever free math-program) or proprietary programs such as Maple or Mathematica from LyX. (By the way Maple 6 is out). MuPAD would be quite nice as it is like Maple. The future lies in nice programs that can import and export XML - files anyway. A nice LyX with full XML filtering capabilities would be in good demand and important in a survival game. This message is of course cheap talk. (= Wild ideas without a single line of code) .

There is a standard called MathML, this excerpt seems relevant:
***
Maple: A computer algebra system from Waterloo Maple Inc. Has
demonstrated import,
export and evaluation of MathML content expressions. Future
support for generation and
rendering. http://www.maplesoft.com
Mathematica: A computer algebra system from Wolfram Research Inc. Will
support
rendering and output of MathML. http://www.wolfram.com
Is automatic translation to and from LaTeX possible ? Is there anything
available which does it ?
Generation of MathML from that in LaTeX documents
(presentation and content) is certainly
possible. Organisations working on this problem include
University of Western Ontario,and the AMS and SIAM.
***
This is from the MathML faq at:
http://www.w3.org/Math/mathml-faq.html#tools
I have no idea about Scilab, Octave, or MuPad. The Scilab people are
active though and I
would expect them to support a standard.
An interesting problem in computer theory. Two different syntactical
designs covering the
same semantic object: how to translate. There probably is no standard
program. Even if
both syntactical designs are BNF defined.

try $\Bbb{R}$ or any other delimiter
it's in mathmode, so $ is needed. for better results,
choose package dsfont and than $\mathds{R}$ or $\mathds{N}$
or any other letter. if it's not installed, than get
doublestroke.zip from ctan or dante.

Most of the interesting programs are scriptable. Maple e.g:
echo "lprint(expand((x+1)^3));" | maple -q
--> x^3+3*x^2+3*x+1
The problem is parsing. First you have to convert from
LyX formula (sort of LaTeX) to Maple syntax which is *not* trivial
since LaTeX does not preserve the logical structure of the formula
- just think about indices etc. Calling Maple is the easy part.
Converting back to LaTeX is not difficult either:
echo "latex(expand((x+1)^3));" | maple -q
--> {x}^{3}+3\,{x}^{2}+3\,x+1
So if you come up with a decent LaTeX parser in C++ I am willing to
implement the easy parts ;-)

wild development ideas
This would belong really to lyx-devel, but I'm not used to use that mailing list... I just found a _great_ symbolic mathematics program called Maxima. It's GNU version of Macsyma, which in turn is over 30 years old software. But it's great, comparable to Mathematica (well, I have never really used Mathematica but at least a lot better than Derive). The user interface isn't just that nice after all. Now, why not integrate[1] Maxima and maybe Octave too to LyX? Imagine writing an equation in LyX, and selecting "solve" from Math menu and your equation would be solved? In any case, some automatic way to transfer data between Maxima<->Octave<->Scilab<->LyX would be great. It's not nice to copy all the numbers by hand between Scilab and LyX, nor formulas between Maxima and LyX. I'm not proposing this do be done immediately, there are more important things to do now (bug fixes and a free GUI, Lesstif would be nice), but maybe sometime in future. We would then have a program superior to Mathematica... [1]Not necessary in the same binary but similarly like DDD is integrated with GDB and Ghostscript with Ghostview/GV.
