The dump_demos.m script does include a simplisitc oct2mat() function.

function code = oct2mat (code)
  ## Simple hacks to make things Matlab compatible
  code = strrep (code, "%!", "%%");
  code = strrep (code, "!", "~");
  code = strrep (code, "\"", "'");
  code = strrep (code, "#", "%");
  ## Fix the format specs for the errobar demos
  code = strrep (code, "%r", "#r");
  code = strrep (code, "%~", "#~");
  code = strrep (code, "assert", "assert4demos");
  endkeywords = {"endfor", "endif", "endwhile", "end_try_catch", "endfunction"};
  for k = 1:numel (endkeywords)
    in = endkeywords {k};
    out = in; out (4:end) = " ";
    code = strrep (code, in, out);
  endfor
  commentkeywords = {"unwind_proect"};
  for k = 1:numel (commentkeywords)
    code = strrep (code, commentkeywords{k}, strcat ("%", commentkeywords{k}));
  endfor
endfunction

Are  you implying there may be a legal liability related to this ? Or, 
something else ?
