if a have a matrix M of dimension (m,n) how do i first check for j columns deep (from left), j<=n for when the ith row will be all zeros eg M=([1,0,1],[0,0,1],[1,1,1]) check j=1 gives output of 1 j=2 gives output of 1 and j=3 gives output of 3
also how do i take out a matrix N of dimension (k,l) k<=m,l<=n out of a the matrix M -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
