NettetIf you have n linearly independent vectors there is no way to make a linear combination of them so that you get the 0 vector in the end other than making them all be multiplied by 0. So in the video the rref vctors were <1,0,0,0>, <0,1,0,0>, <0,0,1,0>. NettetThe linear dependency of a sequence of vectors does not depend of the order of the terms in the sequence. This allows defining linear independence for a finite set of vectors: A …

NettetBowen. 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. NettetRank of Matrix. Determine whether a matrix is full rank. Create a 3-by-3 matrix. The values in the third column are twice as large as those in the second column.
