Nullspace

The nullspace $N(A)$ of a matrix is a subspace of $R^n$ that contains all possible solution vectors to the matrix. It must contain the zero vector to be a Subspace.

Properties

• When $C=\text{[}A;B]$ (a matrix of two or more parent matrices): $N(C)$ are all the intersections of the parent matrices $N(C)=N(A)\cap N(B)\cap \dots$
