Help with TeX parser in text fields

[Rik]

Could someone with access to Matlab run the following code and send me the
resulting pdf?

---Code tst_texparse.m ---
clf;
text (0.5, 0.4, '--]{\bf[0 spaces}', 'interpreter', 'tex');
text (0.5, 0.3, '--]{\bf [1 spaces}', 'interpreter', 'tex');
text (0.5, 0.2, '--]{\bf  [2 spaces}', 'interpreter', 'tex');
text (0.5, 0.1, '--]{\bf   [3 spaces}', 'interpreter', 'tex');
print ('tst_texparse.pdf', '-dpdf');
---End Code ---

I'm trying to determine whether the TeX parser for ignores the initial
space after a backslash command such as \bf for bold font.  The code is
more legible if the command can be separated from the text it operates on,
but we do have to maintain compatibility.

Thanks,
Rik
