cseweb.ucsd.eduThe (right) null space of a matrix A∈Rm×n is the set of all x ∈Rn for which Ax = 0 The matrix Z= null(A) such that AZ= 0 where Z ∈R n×( −r) with orthonormal columns and r = rank(A) ≤min(m,n), is the or-thonormal basis for the (right) null space of A. The columns of Zspan every x in the (right)
The Null Space of a Matrix
sites.millersville.eduThe null space is the same as the solution space of the system of equations Ax= 0. I showed earlier that if Ais an m× nmatrix, then the solution space is a subspace of Fn. Thus, the null space of a matrix is a subspace of Fn. Example. Consider the real matrix A= 3 −1 1 −1 1 1 .
