WebThere are a few points you want to be careful about though. The first one is nitpicky but A is a matrix, and technically the span refers to a set of vectors. Therefore, you should really say Span (columns of A) or Col (A) for column space. Okay so Col (A) = set of lin combos of the column vectors in A. WebWe should be checking that v1+v2 is in the nullspace. What it means to be in the nullspace is that A (v1+v2) should be the zero vector. But A (v1+v2)=Av1+Av2 (because matrix …

As Bill Wallis said, the existence of a zero is important, which is provided by the vectors in the null space. In all practical applications, it is very important that the solutions don't have a component in the null space, which has no effect on the system. Having a component in the null space only wastes resources, which we don't want to do.
