Load an image and divide it into 8x8 matrices

I need to load an image with random dimension and split it into several 8x8 matrices.

I tried with:

[A, map] = imread('arq.jpeg');
[m,n,o] = size(A);
c = mat2cell(A, m*ones(1,8), n*ones(1,8));

But I got this error:

Number of input vector arguments, 2, does not match the input matrix's number of dimensions, 3.

How can I fix this to work with RGB images?

Refer to the code here. You are having the errors as you are missing the third dimension of the matrix (the color space). The code I refernced will show you how to solve the issue.
