In Maple the command NullSpace turns a given matrix into a set of vectors -- a basis for its null space. This is precisely what it should in a mathematical sense. However, for computations using the obtained basis, it would be more convenient to have as output a matrix whose columns are the basis vectors.
I'm having a hard time converting a set of vectors into a matrix whose columns are the given vectors. The order doesn't matter (of course). Any help greatly appreciated.
