I want to show my Peaks inside a plot.

findpeaks seems to be the only thing that can do this.

But unfortunatly I can't get it to work with arrays.

for i =1:15
    [pk_Moment {:,i}, lk_Freq {:,i}] = findpeaks(FFT_Moment {1,i}(:,1), FFT_Freq {1,i}(1,:));
end

Can Anybody show me how it's done?

What error you get with the above?

Invalid use of operator.

The left side should be like this

[pk_Moment{i}, lk_Freq{i}] = findpeaks(FFT_Moment {1,i}(:,1), FFT_Freq {1,i}(1,:));
