Jun 12, 2011 im trying to develop a while loop to get this pattern i know c programming im currently in that class as well but as i said before we dont get matlab trayning in linear algebra so im not familiar with all the commands how do i make a for loop or while loop on a case like this one i know how to do it for other operations, just not in a matrix form.
