stack multidimensional matrices horizontally

Hi everyone

I have a trivial question but a bit tricky to put into code. I have 10 multidimensional matrices each of size 3 x 3 x 30. What I want to do is horizontally stack each of the smaller 3 x 3 matrices from all 10 matrices and form 1 big multidimensional matrix.. so the final size should be like 3 x 30 x 30.

How can i do this?

Thanks,

One approach

A=randi([1 5],3,3,30,10);%demo data
permute(reshape(A,3,30,30),[1 2 3])

Can you explain what the [1 2 3] is for in your code? Thank you for the elegant answer.

Normally reshape would vertically concentenate your matrices. Permute helps me to do ot horizontally and [1 2 3] stands for swapping the 1st and 3rd dimensions.

Got it. Thanks again.
