Here goes. It is based on the original code of M. Koehler, but all
inner loops are vectorized or replaced by more efficient constructs,
and it supports rowformats and columnformats options. Also, it can
take an open file handle instead of a file name.
The docstring is not yet texinfoed.

Typical usage looks like this:

        fid = fopen (...);

        matrix2latex (spw_data, fid, ...
          "columnLabels", {"$y$", "$c$", "$\\alpha$", "$c_{Lp}$",
"$c_{Dp}$", "$c_{mp}$",...
                           "$c_N$", "$c_T$", "$c_L$", "$c_D$"}, ...
          "columnFormats", {"%6.3f", "%6.3f", "%5.2f", "%6.3f",
"%8.5f", "%8.5f", ...
                            "%6.3f", "%8.5f", "%6.3f", "%8.5f"}, ...
          "alignment", "r");

it only produces the matrix code itself, you still need to write the
rest of document, such as:

tex_prologue_dl = ["\\documentclass{report}\n% Created by VZLU 17.12.2009\n",...
"\\usepackage[left=4cm,top=1cm,width=15cm,height=25cm,nohead]{geometry}\n", ...
"% Additional settings\n\\begin{document}\\begin{center}\\small{\n"];
fputs (fid, tex_prologue_dl);

...a number of matrix2latex calls...

tex_epilogue_dl = "}\\end{center}\\end{document}\n";
fputs (fid, tex_epilogue_dl);

I suggest you read a LaTeX tutorial if you're a novice. It takes time
to learn, but pays off a hundred times if you're into this sort of
work. Imagine the nightmare of automatic creation of Word or Excel
documents (yes, I used to do that, too, and I loved LaTeX ever since).
