Hi! I'm having trouble with my Matlab code. When I run the code, it shows this.
Undefined function or variable 'chebwin'.
Error in problem (line 33)
[ps2,freq]=pwelch(data,chebwin(128,100),[],N,Fs);% plotting half of the power spectrum with 50% overlap and chebwin window of length
128
Is this a problem with the toolbox or another issue?

chebwin() needs the Signal Processing Toolbox to be installed and licensed. That is the same toolbox as pwelch, but due to the way MATLAB executes functions, it would not look for pwelch until after it had resolved all the parameters to the pwelch call.
