In the package LinearAlgebra`MatrixManipulation` you will find the answer to your first question and insights into the other. -----Original Message----- From: Jeremy [mailto:cfgauss at pants.attbi.com] To: mathgroup at smc.vnet.net Subject: [mg38544] [mg38543] Appending to a matrix? How do I append a column vector to the end of a matrix in mathematica? For example, I want to turn: [1 2 3] [1] [4 5 6] and [1] [7 8 9] [1] into [1 2 3 1] [4 5 6 1] [7 8 9 1] Or, actually, [1 2 3 | 1] [4 5 6 | 1] [7 8 9 | 1] Not that it really matters. Also, is there a way that I can stick the entries of a row reduced matrix onto powers of x's? Like [1 0 0 | 1] [0 1 0 | 2] [0 0 1 | 3] to 1 + 2x + 3x^2 ? Many thanks, Jeremy --
