FFT code I don't understand

Hi there, I started a project involving EEG data filtering and was given a base code to build upon. When I run it, I get an error:

Undefined function 'movingFFT' for input arguments of type 'double'.

Error in colour_map (line 67) cmapimg = movingFFT(sdt,...

--------------------------------------------------------------------------------------- I looked up and down but that function (movingFFT) doesn't show up anywhere.

I can't attach the files that the code uses (format), but the code itself is there for reference.

Any help is appreciated

I think you've answered your own question. You're missing a function from whoever gave you the code.
