Slicing a matrix into multiple matrices

I would like to slice a matrix and create multipke matrices out of it.

For example,

I've the following matrix

A =rand(10,8)

I would like to slice A based on length of the list N and value of R.

Where,

N = ['a', 'b', 'c', 'd']

R = 2

The expected output is

A.a = A(:,R)

A.b = A(:, R+1: 2*R)

A.c = A(:, 2*R+1 : 3*R)

A.d = A(:, 3*R+1: 4*R)

I'd like to know if there is a better way to implement this.

You can use mat2tiles

Acell=mat2tiles(A,[inf,R])
