Hello everyone,

I'm trying to use the pwelch function, which is part of the signal processing toolbox, but I'm getting an error. Check out the screenshot which shows my licence is valid, but still the function does not run. The script I'm trying to run is an example provided in the matlab help file for pwelch (which does come up when I type help pwelch). Any ideas as to what may be going on?

Thanks! Trevor

Could you execute

which -all pwelch

to see if you have the function installed.

I have the same problem. Matlab returns 'pwelch' not found. How do I install it?

Don’t panic! You could simply have a path problem.

Run these from the Command Window or from your script:

restoredefaultpath 
rehash toolboxcache

Then give your pwelch call another go.

If that doesn’t work, and you’re still having problems, contact Tech Support.

Thanks for the suggestion. That didn't solve the problem, so I've contacted support. I'll let you know how it goes!
