Hi, Call your matrix mat Then Rest[Rest/@mat] will return a new matrix with the first column and first row removed. if you want to have the result in your original variable then mat=Rest[Rest/@mat]. By the way, this is not limited to n by n matrices, this is general solution to any n by m matrix yehuda On 8/2/05, Ramier <wissam2 at online.fr> wrote: > Hello everyone, > > I think that my question is rather simple and maybe I ought to go > deeper into Mathematica book: > I have a n x n matrix and I'd like to remove the first line and the > first column in order to get the (n-1)x(n-1) matrix with the entries > remaining.
