I wanted to know the problems #3 and #5 with Matlab.

Consider the linear equation Ax = 0 for 3 times 3 matrix: A = [1 2 3 2 1 -1 8 7 3]. Form the augmented equation: B = [A | 0]. Perform row operations to determine the row echelon form for B. Determine the corresponding ordered elementary matrices, E_1, E_p. Using Matlab, verify that UB provides the row echelon form determined above, where U = E_p E_1. Determine the reduced row echelon form for B. Use Matlab to verify your solution from part 4
