I'm using the LinearAlgebra package and the Matrix() command to build matrices in Maple 9.5. I need to be able to find the number of rows and the number of columns of a certain matrix A. I ran into problems running nops(A[1,1..-1]) and discovered that if I find the operands of a 3x2 matrix "wem" I am returned this: 3, 2, {(1, 1) = 0.7, (1, 2) = 0.1, (2, 1) = 0.2, (2, 2) = 0.3, (3, 1) = 0.1, (3, 2) = 0.6}, datatype = anything, storage = rectangular, order = Fortran_order, shape = []
