Finding the location of maximum peaks in a plot with MATLAB

Question

Suppose I have the F matrix like this:

F =
0, 0, 106, 10, 14, 20, 20, 23, 27, 26, 28, 28, 28, 23
       |                        |           |
     peak             


        

Answer 1

Well here is what I prefer:

[maxval maxloc] = max(A(:));

Answer 2

Use the findpeaks function (Signal Processing Toolbox).

[peakVal,peakLoc]= findpeaks(x);
