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!
