Check with

 ver

if you have the Symbolic Math Toolbox installed. It is also possible, if you are using a shared license, that it is maybe blocked by another user

Yes the toolbox is missing. Can you tell me from where to download it.

[Andreas Goser]

The same person from your university or company who provided MATLAB to you should also be able to tell you about toolboxes. "Download" alone will not help. You need a license.
