1. The problem statement, all variables and given/known data A = [ 1 0 1 -1 1 -3 2 1 0] what is the column space of A? What is the row space of A What is the solution space of A? Also, if i were given a multiple choice, how do I check if a vector is in either the column, row or solution space of A ? 2. Relevant equations 3. The attempt at a solution From my understanding, the column space is just V1 = (1,-1,2) V2 = (0,1,1) V3 = (1,-3,0) and the row space of A is w1 = (1,0,1) , w2 = (-1,1,-3) and w3 = (2,1,0) . For solution space, i have completely no idea.
