How to add two 3-D matrices?

I have two 3-D matrices of the following size:

Matrix1 = 80 x 95 x 45

Matrix2 = 80 x 95 x 90

I would like to add the matrices such that I end up with 80 x 95 x 135. In other words, for every third dimension, I want to add the numbers in 80 x 95 over and over again until I combine the two matrices to get 80 x 95 x 135. Could someone please let me know how to do this?

Thank you in advance.

out = cat(3,Matrix1,Matrix2)

This is called concatenation:
