Problem 5.
Creating a function for GAUSS ELIMINATION METHOD. The Gauss elimination method is a procedure or numerical method for solving a system of linear equations.
a) Write a user-defined MATLAB function for solving a system of linear equations, [a][x] = [b], using the Gauss elimination method. For function name and arguments, use x = Gauss (a, b), where a is the matrix of coefficients,
b is the right-hand-side column vector of constants, and x is a column vector of the solution. b) Solve the following square system of four equations using the Gauss elimination method.
4x1 - 2x2 - 3x3 + 6x4 = 12
-6x1 + 7x2 + 6.5x3 - 6x4 = -6.5
x1 + 7.5x2 + 6.25x3 + 5.5x4 = 16
-12x1 + 2.2x2 + 15.5x3 - x4 = 17
