How can concatenate matrices with dimension expansion.

img1 = imread('0.png');

img2 = imread('1.png');

size(img1); % (25, 25)

size(img2); % (25, 25)

I want to make 'img' with its dimension (2, 25, 25)

How can I do it?

Answer 1

[David Hill]

Why not 25x25x2?

img(:,:,1) = imread('0.png');
img(:,:,2) = imread('1.png');

Answer 2

permute(  cat(3,img1,im2), [3,1,2]);
