Determine if w is in col a
WebDetermine if the vector u u is in the column space of matrix A A and whether it is in the null space of A A . u = ⎡ ⎢⎣ 2 −1 3 ⎤ ⎥⎦ u = [ 2 − 1 3], A= ⎡ ⎢⎣ 1 −3 4 −1 0 −5 3 −3 6 ⎤ ⎥⎦ A = [ 1 − 3 4... 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[ …

[1,1,4] and [1,4,1] are linearly independent and they span the column space, therefore they form a valid basis for the column space. [1,2,3] and [1,1,4] are chosen in this video because they happen to be the first two columns of matrix A. The order of the column vectors can be rearranged without creating much harm here. sondaschule shirtWebThe point of saying that N (A) = N (rref (A)) is to highlight that these two different matrices in fact have the same null space. This means that instead of going through the process of creating the augmented matrix and carrying around all those zeros, you can find rref (A) first and then find the null space of that.
