[Tex/LaTex] Octave to LaTeX

math-modeMATLABoctave

Is there anything (command/script/function) that can convert a Octave expression to LaTeX.
What I am asking for is something like this:

I type 

a = eye(3,3); %Identity Matrix

and then do something like textify_me(a) which produces

\begin{array}{ccc}
1 & 0 & 0 \\ blah blah blah
\end{array}

AND/OR

syms x
int(sym('x^2'))

produces

\frac{x^3}{3}

I am not asking for "sweaving" of codes, exporting figures or anything similar. I am simply asking for conversion of variables and symbolic expressions directly to LaTeX format.

MATLAB has a function latex which does this. But it is closed source. Is there something Open Source or should I attempt to try and accumulate people to write it?

Best Answer

If all you need is a matrix, you can do this:

strrep(strrep(mat2str(A),",","&"),";","\\\\\n")(2:end-1)

where A is your matrix. That will give you the body of your matrix, without the \begin{matrix} and \end{matrix}

strcat("\\begin{bmatrix}\n",strrep(strrep(mat2str(A),",","&"),";","\\\\\n")(2:end-1),"\n\\end{bmatrix}\n")

will generate the whole thing.

I don't think there is a more comprehensive solution in Octave.

Another option seems to be using scilab. It is also more or less MATLAB compatible (some say even more than Octave), and it has a prettyprint function that seems to do what you want. I have no experience with scilab, though.
