MATLAB: How to create a 3-d matrix from a 2-d matrix

Question

My matrix is an 11×14 matrix and I would like to create 2 more "pages" behind the original of the same values for a total of 3 "pages". Is there an efficient way of doing this? This needs to be done for several matrices.

Answer 1

Another way is to use cat(3,...) instead of repmat():

output = cat(3, myMatrix, myMatrix, myMatrix);

or "If I have the A(:,:,2) matrix and want to replicate those values into A(:,:,1) and A(:,:,3),"

A(:,:,1) = A(:,:,2);
A(:,:,3) = A(:,:,2);
