Gregory - Suppose your list is called "mymats". Then
Reduce("+",mymats) does what you want. - Phil On Sun, 12 Sep 2010, Gregory Ryslik wrote:
Hi, I have a list of several hundred 2 dimensional matrices, where each matrix is n x m. What I need to do is that for each n,m I need an average over all the lists. This would collapse it down to just one nxm matrix. Any easy ways to do that? As always, I'd like to avoid a for loop to keep computational time low! Thanks again everyone!
