How can I make a few matrices have the same size?

I have a few (well 188) matrices and they are like:

A: 207x79x256 B: 171x92x256 C: 162x95x256 D: 188x85x256 and so on

How can I cut all of then to have matrices with the same size? Preferably at once...

Thanks

You need to add more detail. For example, do want to remove elements from the larger ones, or pad elements (zeros?, NaNs?) to the smaller ones? You do say "cut", but then details about how are important. From the "top" or "bottom", for example.

Also, do you have the ability to rewrite the code that led up to this poor choice of names, A, B, C, ... ? It seems your data model could have been chosen better. For example, you might have chosen to use cell arrays, such that they are stored as A{1}, A{2}, A{3}, etc. Or maybe even have used a single 4-dimensional array.

If you have different matrices of different sizes, you likely cannot do all of them at once.

If you want to make them the same size, just define them that way:

A = rand(7,5,3)
Anew = A(1:5, 1:3, 1:2)
