"Findpeaks" function doesn't work

when running the following code using Matlab on my PC: " x=[1,2,3,2,1]; [val,place]=findpeaks(x) " I get this error: Undefined function 'findpeaks' for input arguments of type 'double'.

however, when running the exact same code in my office (different license, different computer) it works just fine. I have had this problem in the past, and re-installing Matlab seemed to solve it. Now I have the same problem and I don't think re-installing it would be a proper solution. Any solution?

findpeaks belongs to the signal processing toolbox. If you do not have a license for this toolbox, you cannot run this command.

I have the license but for some reason the toolbox was uninstalled. Thank you.
