Function does not work despite having lisence
显示 更早的评论
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.

My pleasure. Also, my sympathies. I hope you can avoid reinstalling.
