Question: Write a program for the Gauss elimination with pivoting. Apply it to Probs. 1316. Experiment with systems whose coefficient determinant is small in absolute value.

Write a program for the Gauss elimination with pivoting. Apply it to Probs. 13–16. Experiment with systems whose coefficient determinant is small in absolute value. Also investigate the performance of your program for larger systems of your choice, including sparse systems.

Data from Prob. 13

Solve the following linear systems by Gauss elimination, with partial pivoting if necessary (but without scaling). Show the intermediate steps. Check the result by substitution. If no solution or more than one solution exists, give a reason.

3x₂ + 5x₃ = 1.20736
3x₁ - 4x₂ = -2.34066
5x₁ + 6x₃ = -0.329193
