WebDe nition 1. The nullity of a matrix A is the dimension of its null space: nullity(A) = dim(N(A)): It is easier to nd the nullity than to nd the null space. This is because The number of free variables (in the solved equations) equals the nullity of A: 3. Nullity vs Basis for Null Space There is a general method to nd a basis for the null space: WebWe have given definition of row space , column space , null space of a matrix . (.)

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 transformations are linear). Now if we assumed v1 and v2 are in the nullspace, we would have Av1=0 and Av2=0. So A (v1+v2)=Av1+Av2=0+0=0.
