http://web.mit.edu/18.06/www/Fall07/pset6-soln.pdf WebThe vectors [-1 1 0] and [-1 0 1] are linearly independent vectors in the nullspace of A. A is a rank 1 matrix, since there is only one pivot variable c1 and two free variables c2 and c3. So, we have rank (A) = r = 1. dim (colspace (A)) = dim (rowspace (A)) = r = 1 colspace is subspace of R1 rowspace is subspace of R3 high end fleece top vancouver kitsilano
