1 MACM 316: HOMEWORK ASSIGNMENT 4 Due Date: November 11, 2009 (by Noon) Sections and Problems: § 6.5 # 6a, 10 In the last assignment, you used your Gaussian elimination program to solve the problem Hx = b , where H is the 8 × 8 matrix. H = ( h ij := 1 i + j - 1 ) , i, j = 1 , ··· , 8 and b = ( b i := 1) , i = 1 , ··· , 8. Running a slightly modifed version oF your program, determine whether or not there was any pivoting (any row interchanges). With this inFormation, fnd the
