Hey everyone,
I need to convert a 2D into a 3D matrix. The initial dimensions are nx64 (the first number is always random) and it needs to be transformed into 4x16xn, but in this order:
1 5 9 13 17 ... 61
2 6 10 14 18 ... 62
3 7 11 15 19 ... 63
4 8 12 16 20 ... 64
and
1 2 3 4 5 ... 16
17 18 19 20 21 ... 32
33 34 35 36 37 ... 48
49 50 51 52 53 ... 64
The third dimension should be the n rows from the original matrix. Can someone help me with both cases?

You can use reshape to convert 2D matrix into 3D. But remember that the number of elements should not vary.
clc; clear all;
d = 1:64 ;
% 2D matrix
d2D = reshape(d,4,[]) ; % let the MATLAB decide the number of columns
% 2D to 3D
d3D = reshape(d2D,4,8,[]);
% fix the number of rows and columns and let matlab decide the number of matrices in 3D
