[GAP Forum] Find rank-1 matrices in given subspace of matrices

[Benoit Jacob]

Hello,

What would be a good approach to obtain a parametrization of the set of all
rank-1 matrices in a given subspace of matrices M_n(F), where F is a finite
field?

It seems that what I'm looking for is equivalent to Maple's Rank1Elements()
function

.

Thanks,
Benoit
