How do i extract data from 3D matrix?

I have a matrix of size 256*256*256, i want to create a 2D matrix whose each row has information from the z direction of the original matrix, how do i do it?

[James Tursa]

Please give us a small example of what you want. E.g., start with a 2x2x2 array and then show us the resulting 2x2 matrix you want as an output. Maybe all you need is sum(matrix,3) or mean(matrix,3), but we can't tell from what you have written so far.

Hi James,

Here is an example of what i want (only my A is 256*256*256)

>> A

A(:,:,1) =

1 2

3 4

5 6

A(:,:,2) =

7 8

9 10

11 12

A(:,:,3) =

13 14

15 16

17 18

>> iwant

iwant =

1 2 3 4 5 6

7 8 9 10 11 12

13 14 15 16 17 18

[m,n,~] = size(A);

newA = reshape(permute(A,[2 1 3]),m*n,[]).';
