I have 2 matrix, A(m,n) and B(o,p). which m=o and n=p, then n and p depend on user input. if input = 3 then n = p =3, if input =10 then n = p =10, and so on. Now, i wanna create matrix C which consist of A and B with the structure like this C=[A(:,1) B(:,1) A(:,2) B(:,2) ...A(:,n) B(:,p)] how can i create that matrix, with n and p depend on user input?iam confuse...please help.
thanks in advance.

% So you have 2 matrices that are the same size.
A = rand(4,5)
B = rand(4,5)+50
% Stack them on top of each other
C = cat(1, A, B)
% Rearrange them to have the same 1st dim size as the original
C = reshape(C, size(A,1),[])
You see here that the "C" variable has columns like you requested C=[A(:,1) B(:,1) A(:,2) B(:,2) ...A(:,n) B(:,p)]

I am also confused. Let's say that the user gives you two matrices A and B. It seems like you need to insert columns of one matrix between columns of another (lust like mixing the playing cards). Since both matrices will be the same size we can do the following:
[m n]=size(A);
C=zeros(m,2*n);
k=1;
for x=2:2:2*n
C(:,x-1)=A(:,k);
C(:,x)=B(:,k);
k+1;
end
