How to draw a Histogram in Matlab

by

This should work just fine if you don’t want to use some predefined functions:

una=unique(a);
normhist=hist(a,size(unique(a),2))/sum(hist(a));
figure, stairs(una,normhist)

Una has only the unique values of a, normhist is now between 0 and 1 and it’s the probability of occurring of the individual signal because you divide it by the number of elements included in the data.
