I want only part (e) MATLAB code

3) Consider solving the linear system 2x1+x2x3+2x4=54x1+5x23x3+6x4=92x1+5x22x3+6x4=44x1+11x24x3+8x4=2 (a) Compute the determinant. (b) Use Cramer's rule to solve for the x 's. (c) Use Gauss elimination with partial pivoting to solve for the x 's. (d) Substitute your results back into the original equations to check your solution e) Develop a M-file for above question (Gauss elimination)
