Hi,
I have generated some spectrograms and i want to display 'velocity' instead of 'frequency' on y-axis. Sample code is given below. My wavelength is 0.0039 meters. How can i do this? Kindly guide
load('data.mat');
x = sum(data/max(max(abs(data)))); %normalizing bw 0 and 1 and summing across rows
figure();
c=jet(256);colormap(c);
spectrogram(x,hanning(512),487,1024,12.4e3,'centered','yaxis','MinThreshold',-50);
