Changing two variables in a for loop
显示 更早的评论
Hi,
I would like to change two variables in a for loop. I have a matrix A and would like to create a new matrix that looks like:
A(1,1) 0 0 0 A(1,2) 0 0 0 A(1,3) ...
A(2,1) 0 0 0 A(2,2) 0 0 0 A(2,3) ....
Where the new matrix is 4 times as many coloums as the original matrix and the same number of rows (in the end 139 x 3774).
What is the best way to do this?
Thanks in advance for your help.

Try this:
B = zeros(size(A,1),4*size(A,2));
B(:,1:4:end) = A;
