Hello,
I keep getting the following error when I try to do a spectrogram: Subscript indices must either be real positive integers or logicals.
Error in getSTFTColumns (line 14) xin = x(rowindices+coloffsets);
Error in pspectrogram (line 55) [xin,t] = getSTFTColumns(x,nx,nwin,noverlap,Fs);
Error in spectrogram (line 168) pspectrogram({x},'spect',varargin{:});
This is what I am doing:
% Trying to use this code: spectrogram(x,window,noverlap,f,fs) so that I can see the spectrogram in terms of frequency and time
% x is my signal
% fs = 128
% N = 15360
% The frequency range I want to look at is between 2-35Hz
figurespectrogram(x,hanning(2*fs),0.5,[2 35],fs)
