"It came from Row Space!"
Summary:
The Row Space of A, like Column Space, is a place we need to know about too. All solutions to A→x=→b where →b≠→0 have to come from somewhere that is not Nullspace. We show that subspace formed by all linear combinations of the rows of A is the right elsewhere. Many, many exciting, heartbeat-skipping discoveries follow including that Row Space of A is the Column Space of AT.
