I have a 3D matrix, which is a model of the porous media of a rock. I want to extract three 3D matrices from it so that each contains the 2D slices in a specific direction, for example x. To be clear, the matrix x contains the 2D slices in x direction, y in y-direction and z in the z-direction. I appreciate any hint or help to solve my issue.

Suppose you have G, which is a Y-by-X-by-Z 3D array, then

i-th xy slice:

G_yx=G(:,:,i); % Y-by-X array

i-th xz slice:

G_xz=permute(G(i,:,:),[2 3 1]); % X-by-Z array

i-th yz slice:

G_yz=permute(G(:,i,:),[1 3 2]); % Y-by-Z array
