[GAP Forum] A question about rank of a matrix

[Rahul Kitture]

Dear Experts,

I had a simple question about rank of matrices over finite fields in GAP.

Suppose A and B are matrices (over a finite field GF(p)), considered in GAP.

Assume that A and B have *same number of rows*.

Then I want to consider the matrix obtained by putting B after A (i.e. the
matrix [A B]; it has same  number of rows as A; but number of columns is
(number of columns of A) + (number of columns of B)) and study rank of [A
B].

What is the command to do this?

I did  *gap > RankMat([A,B]); *

But it was showing error.


Thanks in advance!
