How can i skip the zeros in a matrix?

1 view (last 30 days)
Hi, I have a matrix with columns filled with zeros and i want to copy the matrix into a new matrix but to skip the columns with the zeros. Is there any command that can help me? I tried to do it with the sparse command but i didn't really understand what happens there. It skips the zeros but when you want to know how many columns you have in the new matrix it still shows the initial size. thanks in advance!
