Paolo, mat = Array[x, {4, 4}] To extract the 3rd column as a vector just use... Part[mat, All, 3] If you are a new user you will probably save yourself some time by reading through the first two sections of the book and becoming familiar with the various Mathematica commands that are available. I know, there are a lot of them so it isn't easy at first. David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: paolo tarpanelli [mailto:tarpanelli at libero.it] To: mathgroup at smc.vnet.net How can i extract a column from a matrix and transform that column in a vector to make operation with this??? Thanks Paolo
