RE: Merge of Matrices
Roman, Try the standard package LinearAlgebra`MatrixManipulation`. David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: Robert Berger [mailto:rberger06 at sinh.us] To: mathgroup at smc.vnet.net Hello! I like to create from the four matrices A (N1 rows and N1 columns), B (N1 rows and N2 columns), C (N2 rows and N1 columns), D (N2 rows and N2 columns) a new matrix X of the form A B X = C D Once A & B and C & D have been merged, the first (A & B) and the second row (C& D) can be merged in that way by applying Join, which is not a problem but how can I merge A & B (and of course C & D) in that way? Kindly regards, Roman.
