hi, im having problems understanding the pspectrum function for matlab. I obtain data for 60seconds. each sample i obtain the amplitude and the associated timepoint. So i get 2 matrixs(amplitude matrix and time matrix). now i want to see the spectogram of this signal using pspectrum. i understand that it is possible to devide the data into windowsegments and specify an overlap. but i dont quite know how to do this. also what should i give as input argument(amplitude matrix, time matrix, both) and how to specify the frequency resolution? so the arguments i want to give are: windowlength, overlap, input argument(amplitude,time or both), frequency resolution. and from that i want to see the spectogram.
thanks in advance
kind regards
