Unable to Access Signal Processing Toolbox Functions

Hey all,

I recently installed matlab and the signal processing toolbox for a class I am taking. However, when I try to use a function from this toolbox, I am met with "undefined function or variable 'xxxx'".

I have confirmed with ver that I have both matlab and the toolbox installed, and confirmed with license that I have the license for the toolbox.

>>  zvect([1 + j, j, 3 -4*j, exp(j*pi), exp(2j*pi/3)])
Undefined function or variable 'zvect'.

Anyone know what the problem might be? Please help, I just spent $60 on software that isn't working.

First, run these from a script or your Command Window:

restoredefaultpath 
rehash toolboxcache 

Then try using the Signal Processing Toolbox functions again.

If your’e still unable to use them, click on the telephone handset icon in the upper right corner of this page to Contact Support.
