3’rd columns, is a basis of the column space of A. The reduced row echelon matrix in the homogeneous system is . Thus, is a basis for the null space of A. Since the bases of the column space or row space of A consist of 3 vectors and the basis of the null space of A consists of 1 vector, then . Note: In the above example, 2.

the null space of is the orthogonal complement of the column space of A. [Intuition of the result:] If (x. is the solution of ), then . Thus,, for That is, x. is orthogonal to the column space of . Therefore, Example: Let . A in reduce row echelon form is . The basis for the null space of A is . and the basis for the row space …

Row Space, Column Space, and Nullspace. In this computer lab we study important vector spaces associated with matrices. Example: Find bases for (a) the row space, (b) the column space, and (c) the nullspace of the following matrix: Solution to (a): Enter the 4 by 6 matrix, naming it . A. We use the fact that the nonzero rows of the reduced ...

(3) The row space of A (the column space of AT), R(AT) (4) The left null space of A, N(AT), contains all vectors : y . AT = 0. The row space of A R(AT) has the same dimension r as the row space of U and it has the same bases because the two row spaces are the same. The null space of A N(A) is the same as the null space of U.
