My question is pretty general. I keep getting the following error when I try to run my simulation:
??? Undefined function or method 'FFT' for input arguments of type 'char'.
I am not sure why I am getting this error, as I am not explicitly calling on the FFT function. I did some background reading on this error type and found out that it has to do with specifying the correct path name.
The thing is, I am calling a user defined function called "fft1", which is an "altered" version of the discrete fourier transform. fft1 uses the actual fft function that is provided by MATLAB.
Can anyone help me fix my problem? I feel like I have set the path correctly, but I continue to get this error. Does it have something to do with my fft1 function?
