WebDimension & Rank and Determinants. Definitions : (1.) Dimension is the number of vectors in any basis for the space to be spanned. (2.) Rank of a matrix is the dimension of the column space. Rank Theorem : If a matrix "A" has "n" columns, then dim Col A + dim Nul A = n and Rank A = dim Col A. Example 1: Let .

WebMar 27, 2015 · 6. You could form the projection matrix, P from matrix A: P = A ( A T A) − 1 A T. If a vector x → is in the column space of A, then. P x → = x →. i.e. the projection of x → unto the column space of A keeps x → unchanged since x → was already in the column space. ∴ check if P u → = u →.
