3D hypercube to 2D array

Hi,

I have a 3D hypercube of dimensions 250x250x150 and I am looking to make it 2D, expanding left to right along the 250x250 array to create a new array that is 62500x150. Would reshape(A,62500,150) work? I would essentially like my z-coordinate to become my y, and the x and y to become x.

Thanks in advance.

No, If you want to read the elements left to right then first you need to permute the 1st and 2nd dimensions

A; % 250x250x150
B = reshape(permute(A,[2 1 3]), [], 150);

Thanks!!

And what's the best way to convert back?

Does

C = permute(reshape(B,250,250,150),[2 1 3])

work?

Yes, thats correct.
