Web5.1 Video 1. Theorem: Let A A be an m ×n m × n matrix. The orthogonal complement of the row space of A A is the null space of A, and the orthogonal complement of the column space of A A is the null space of AT A T: (RowA)⊥ = NulA ( Row A) ⊥ = NulA and (ColA)⊥ = NulAT ( Col A) ⊥ = Nul A T. WebThe successive null space projector Nsuc 2(q) is obtained by evaluating Nsuc 2(q) = I J1(q)T(J(q)#)T; (4) wherein fg#represents the generalized inverse and Iis the identity matrix. Analogous to (3), the remaining tasks in the hierarchy (2
