PPT-Subspaces associated with a Matrix

Hungyi Lee Reference Textbook Chapter 43 Three Associated Subspaces A is an m x n matrix Basis Dimension Col A Null A Row A in R m in R n in R n Col A T A A Zero vector range. It is essential that you do some reading but the topics discussed in this chapter are adequately covered in so many texts on linear algebra that it would be arti64257cial and unnecessarily limiting to specify precise passages from precise texts The 4 KRYLOV SUBSPACES AND CONJUGATE GRADIENTS 2006 Gilbert Strang 64 Krylov Subspaces and Conjugate Gradients Our original equation is Ax The preconditioned equation is Ax When we write we never intend that an inverse
