how can I evaluate the FWHM in a histogram with 2 peaks or more? I couldn'f find a built-in function...
thanks!

Since there isn't a builtin function, you will have to write one yourself.
I would suggest starting with finding the peak.

Try this (untested):
counts = histcounts(data);
maxCounts = max(counts);
leftBin = find(counts > maxCounts/2, 1, 'first')
rightBin = find(counts > maxCounts/2, 1, 'last')
fwhm = rightBin - leftBin; % Add 1 if you want, depending on how you define width.
