Use the geometric method to solve a linear programming problem.
You solve a non-singular system of 1,000 linear equations with 1,000 unknowns. Your code uses the Gauss-Jordan algorithm with partial pivoting using double precision numbers and arithmetics. Why would the 2-norm of the residual of your solution not be zero?
a) Solve the following system using naive Gaussian elimination with three digits (rounded )arithmetic and compare the result with the exact solution x1 = 1.00010... and x2 = 0.99989...
10^(-4 *)x1 + x2 = 1
x1 + x2 = 2
b) repeat a)after interchanging the order of two equations
