MATLAB: Max value of each vector in a 3D hyperspectral data matrix

Question

I have 3D datacubes (hyperspectral images), and would like to come up with the position of the maximum value in each of the vectors along the z dimension.

So for every pixel with (x,y) coordinates, I want to know what the position is of the maximum value in the (x,y,:) vector, the max. of all z values).

is there a way to do this without running a for-loop with find?

Thanks!

Answer 1

Let's say xc is your datacube, does

[z_max,z_ind] = max(xc,[],3)

satisfy your needs?
