WebAug 19, 2024 · 1) We see that the row and column rank (they are always equal) are 3 . The nullity = n − rank = 4 − 3 = 1 . To find the null space we have to solve A x = 0, and this is easy now in row reduced form x = [ 0 0 0 a]. 2) The row space has dimension 3 as mentioned, for the basis one can take: ( 1, 0, 0, 0) ( 0, 1, 0, 0) ( 0, 0, 1, 0) WebBowen. 10 years ago. [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.
