Concatenate correlation matrices/tables across subjects to one 3D matrix

I have n correlation matrices of the same size (400x400) and the same variables which are stored as .mat tables and I want to create one 3D matrix across all of my n subjects. I tried to concatenate them but it does not work.

Thank you for helping!

cat(3,m1,m2,m3,m4...)

concatenates m1,m2,... along third dimension.

Thank you. That is what I've tried before and it did not work. But I found the problem: I had to transform the mat tables to arrays and now it works.
