Write and call a Matlab function to solve a system of equations with Gauss Elimination with

partial pivoting. Be sure that your code can accommodate $10$ equations if necessary. Test the

program using the following system. Print the values of $x_1,x_2$ and $x_3.($soln: $x_1=x_2=x_3=1)$

$x_1+2x_2-x_3=2$

$5x_1+2x_2+2x_3=9$

$-3x_1+5x_2-x_3=1$
