Using Imagesc() then solving for the locations of the max values

Hi,

So I am trying to go from an imagesc() plot to finding the coordinates of the maximum values of the coordinates in the plot. I attached my code and the imagesc() plot I am trying to find the maximum values from. If this doesn't make sense feel free to ask me questions!

Thanks!

Matlab Code:

x = [1; 2; 3; 4; 5; 6; 7; 8; 9; 10];

y = [1; 2; 3; 4; 5; 6; 7; 8; 9; 10];

z = [40 2 3 4;

40 40 6 8;

3 40 40 12;

4 40 40 16;

5 40 40 20;

6 40 40 24;

7 14 40 28;

8 16 40 40;

9 18 40 40;

10 20 30 40];

N = imagesc(x, y, z);

L = max(z,[],2);

[I,J] = find(z==max(z(:)))

For example, for exery location there is a red box (a maximum of 40), a x and y point would correspond to it.
