Follow-up Comment #2:

Hi,

Thanks for your report. I think you are right that labels that are generated
by Octave itself could be handled by Octave. Changing text provided by the
user is another story:
* Octave has a "tex" interpreter, which means it can handle a *subset* of
latex formatting, in line (without the need for $). So far so good. 
* Octave doesn't have a "latex" interpreter (in the background, it is the same
as "tex"). But if it had, "function of e^x." would not be a valid expression
for the "latex" interpreter. The user would have to enclose the inline math
expression between $ himself.

So I think someone who wants to print using latex output formats should take
care of having valid text strings himself (as will be necessary when a proper
latex interpreter is implemented), except for those generated by Octave
itself. 
For those, a workaround is to use something like :


function fixlabels (hax)
  for s = ['x' 'y' 'z']
    if (strcmp (get (hax, [s "scale"]), "log") &&
        strcmp (get (hax, [s "ticklabelmode"]), "auto"))
      labs = get (hax, [s "ticklabel"]);
      labs = cellfun (@(ss) ["$" ss "$"], labs, "uniformoutput", 0);
      set (hax, [s "ticklabel"], labs)
    endif
  endfor
endfunction
