MATLAB Central Newsreader - MATLAB Publishing of Symbolic Equations through TEX

MATLAB Publishing of Symbolic Equations through TEX

Brandeis — Mon, 21 Jan 2008 21:16:01 -0500

I am using MATLAB's publishing feature to document my
MATLAB code. For many of my equations I have inserted TEX
strings so that when the documentation is created, the
equations are displayed symbolically.

I have noticed that when MATLAB publishes the results, it
automatically creates a ".png" file for each symbolic
equation that you specify in your comments. MATALAB seems
to assign a random name to each of these ".png" files it
creates for symbolic equations. Is there a way to control
what it names each of ".png" file that is created for a
symbolic math equation that is published by MATLAB?

Sorry, nope. Why does this matter to you?

We are using a tool to automatically convert MATLAB code
into real time C code. I am also using the publishing
feature of MATLAB to automatically create the algorithm
description document for the MATLAB code.

Since the auto-generated C code keeps MATLAB comments
intact, the MATLAB "publishing tags" are retained. I wrote
a MS-Word VBA macro to suck the auto-generated C code into
MS-Word. The VBA macro catches the "publishing tags" in
the auto-generated C code and insert the appropriate hyper-
text links, image, or formatting. The only hangup is when
the VBA maco encounters the tag for a symbolic equation,
it can not figure out which corresponding ".png" equation
file to insert into the word document.

The idea is to basically have a published version of the
MATLAB code and a published version of the auto-generated
C code that match (i.e. have the same symbolic math
equations and formatting).

If I can just get MS-word to recognize TEX strings that
would also work, but that is a MS-Word issue, not a MATLAB
issue.

OK, I'm with you. Thanks for the detail.

The filename is generated by hashing the actual text of the
TeX. See toolbox/codetools/private/hasEquation.m for the
simple algorithm. You should be able to do this same
calculation in VBA.

(I'll also give you a heads up that the hash function we use
is changing in the next release to something more
complicated, so you'll have to look at this again in the
future.)

Thanks for the info; however, I could not find a codetools
subdirectory under toolbox. I am using 2007b. Could it be in
a different location? I tried a search in all the MATLAB
directories and still did not find the file

Thanks, Brandeis

Ok,

I found the file ok. It is hashEquation.m

Please disregard previous post. Thanks
