Determine if w is in col a
WebI think this way is easier and more general: To find the column space of a matrix, you don't need to use an augmented matrix. Just use column reduction, which will get you to: $$\left[ \begin{array}{ccc} 1&1&-3\\ 0&2&1\\ 1&-1&-4 \end{array} \right] \sim \left[ … WebIf b is in Col A = Col [ 2 − 6 − 6 4 2 − 8 6 − 2 − 2] then b = c 1 [ 2 4 6] + c 2 [ − 6 2 − 2] + c 3 [ − 6 − 8 − 2] = [ c 1 c 2 c 3] [ 2 − 6 − 6 4 2 − 8 6 − 2 − 2] For some c 1, c 2, and c 3 so being in the column space is the same as having a solution to the system A x = b Share Cite Follow answered Jun 25, 2013 at 1:12 Sean Ballentine 1,039 6 13
