Hey
I have a 3d matric with size 359x180x360.
I want now to create a new matrix with size 359x180x360 where all the elements have percentage of a specific value, so a simple example:
A(:,:,1) = [7, 8, 12; 4, 13, 5; 11, 12, 12]
A(:,:,2) = [11, 9, 12; 6, 12, 8; 15, 15, 2]
And I want the new matrix with the percentage of values greather than 10 so I get a matrix like:
B(3,3,1) = [50, 0, 100; 0, 100, 0; 100, 100, 50]
Anyway to do that?

There's no point in the output array having P planes...
V=value;
[~,~,N]=size(A);
B=100*sum(A>V,3)/N;
