Suppose that v1, V2, . . . , Vn are linearly independent column vectors in F“:* and let e1, e2,..., en be the orthonormal vectors that result from the Gram-Schmidt process. (a) Show that there exist aj, E F such that: Vj = aj,1€1+..ɑj jej +0ej+1+...+0en for each j= 1, ...,n. (b) Let B be the n xn matrix in IF," such that column j of B is vj. Let Q be the n x n matrix in F"," such that column j of Q is ej. Use your answer in (a) to find an upper triangular matrix R such that B=QR.
