Differential Equations and Linear Algebra, 5.1: The Column Space of a Matrix, A

Column Space and Nullspace | Linear Algebra | Mathematics | MIT OpenCourseWare

Construct a matrix with the required property or say why that is impossible. (a) Column space contains [ 1 2 -3] and [ 2 -3 5], nullspace contains [ 1 1 1]. (b) Row space contains [ 1 2 -3] and [ 2 -3 5], nullspace contains [ 1 1 1]. (c) A x=[ 1 1 1] has a solution and A^T[ 1 0 0]=[ 0 0 0]. (d) Every row is orthogonal to every column ( A is not the zero matrix). (e) The columns ad
