Slow symbolic toolbox startup in MATLAB 2009a

May 21st, 2009 | Categories: matlab | Tags:

One of the many jobs that I have to do is to package a version of MATLAB for distribution to my employer’s standard student Windows desktop image and so I got to test MATLAB 2009a on Windows for the first time.  While testing the deployed version of MATLAB I discovered that it seemed to hang when you tried to initialise the symbolic toolbox.

For example, typing


into MATLAB should start the mupad notebook but it just sat there for over 10 minutes before I got bored and terminated the process.  Similarly, if you type

syms x

to set the variable x as a symbolic variable then it just seems to hang.  At first I thought there was something wrong with my deployment method but it turns out that it’s a bug in MATLAB 2009a.

Happily, it’s a bug that Mathworks knows about and they have provided a workaround.  Unhappily, you need to regsiter for a Mathworks account to get access to the zip file containing the workaround.

    Hi danton

    I used my Mathworks account to get the zip file mentioned in the last paragraph of the post. Worked perfectly

    The symbolic toolbox *is* available for 2009a but you have to pay extra for it.
