matlab particleswarm not found

Hi.

Is there any update on Matlab recently? I have codes that use particleswarm function and worked perfectly. However today Matlab keeps returning error "Undefined function or variable 'particleswarm'" eventhough I did not make any change. When I tried 'help particleswarm', I got "particleswarm not found" message.

I need a confirmation that the problem is with Matlab, not my codes.

I am using Student Version license. So for now, I assume that the problem is due to license expiry.

Thank you for your help.
