How can I identify the x-values at which the first difference peaks?

As you an see above, the first difference peaks at 8 values. What do i input to identify those 8 values. This is what I have so far to obtain the first difference (bla is what I defined my data as):

>> clear idx

thr = 4500;

m=1;

for ii = 2 : length(bla)

if bla(ii) > thr

idx(m,:) = ii;

m=m+1;

end

end

>> plot(diff(idx))

Try findpeaks

Hi,

Those 8 peak values of the variable bla can be obtained with:

Peaks_bla = bla(idx);

Good luck.
