I agree that octave is not the ideal tool for working with lots of
text.  awk, perl, sed, and other tools are more useful for these
kinds of tasks.  However, if you are only dealing with a few simple
strings, I will at times just do some of this stuff in octave.

For example:
\begin{octave->latex}

outfile = "myoutputfile.dat";

mydata = [0.15, 0.22, 1.2, 320, 22;
          0.15, 0.22, 0.9, 293, 24;
          0.15, 0.22, 1.2, 290, 26];

numrows = rows(mydata);

fpwrite = fopen(outfile, "w");

fprintf(fpwrite, "\\begin{table}[t]\n");
fprintf(fpwrite, "\\centering\n");
fprintf(fpwrite, "\\begin{tabular}{|c|c|c|c|c|}\n");
fprintf(fpwrite, "\\hline\n");
fprintf(fpwrite, "xpos (mm) & ypos (mm) & voltage (V) & temperature (K) 
& thickness (Angstroms)\\\\\n");
fprintf(fpwrite, "\\hline\n");

for ii = 1:numrows
  fprintf(fpwrite, "%#4.3g & %#4.3g & %#5.4g & %#5.4g & %#5.4g\n",
                     mydata(ii,1), mydata(ii,2), mydata(ii,3), 
mydata(ii,4), mydata(ii,5));
endfor % ii

fprintf(fpwrite, "\\hline\n");
fprintf(fpwrite, "\\end{tabular}\n");
fprintf(fpwrite, "\\caption{Completely made up data}\n");
fprintf(fpwrite, "\\label{mytable1:myexample}\n");
fprintf(fpwrite, "\\end{table}\n");

fflush(fpwrite);
fclose(fpwrite);

\end{octave->latex}

Not pretty, but it can get you going if you do not have the
other tools available.  I suggest awk since it is pretty easy
to learn and use and it works on almost all platforms with
a rather small footprint.
