Let say I have Matrix M with i rows and j columns. And one constant number a is given. Final output Matrix should be N with rows = i * a and column = j / a, and Each column in N should be concatenation of its a columns. Is it possible to get this without loops ?
For example:
M =
1 3 5 7 9 11
2 4 6 8 10 12
N with constant a = 2 should be
N =
1 5 9
2 6 10
3 7 11
4 8 12

You can write more general code using following code:
N=reshape(M,size(M,1)*a,size(M,2)/a);
