A = rand(128,4626);
B = rand(128,4626);
I would like to concatenate A and B together, but in this format: C = [A(:,1) B(:,1) A(:,2) B(:,2) ... A(:,4626) B(:,4626)]
Is this possible?

A = rand(128,4626);
B = rand(128,4626);
[m,n] = size(A) ;
iwant = zeros(m,2*n) ;
iwant(:,1:2:end) = A ;
iwant(:,2:2:end) = B ;

Ran in:
A = randi(10,2,3)
A = 2×3
4 2 1 2 2 4
B = randi(10,2,3)
B = 2×3
7 1 7 4 3 2
reshape([A;B], size(A,1), [])
ans = 2×6
4 7 2 1 1 7 2 4 2 3 4 2
