Q1. Show all workings.

Don't count the number of divisions. Do not use asymptotic notation, instead provide exact answers.

(i) What is the maximum number of multiplications required to solve a system of n equations with n unknowns using Gaussian Elimination

(ii) What is the maximum number of multiplications required to obtain the determinant of ann by n matrix by L.U. Decomposition using Gaussian Elimination.

(iii) What is the maximum number of multiplications required to invert an n by n matrix using Gaussian Elimination.

(iv) For what range of values of w is the Gaussian-Siedel method stable when solving this system of equations:

3x - y + wz= 3

x + 3y -z = 4

x + y -2z = 1

Q2. Write a procedure to obtain the inverse of an n by n matrix using Gaussian elimination. (You cannot use A^-¹or any of the built-in packages like 'MatrixInverse'.)

Output any appropriate error statements. Test your procedure on each of these matrices
