Write the following MATLAB functions
(a) function l,u¸=naivege(a) that returns the lower triangular matrix L and an upper triangular matrix U such that A=LU, obtained by Gauss Elimination without pivoting.
(b) function x=utrisol(u,b) that solves the upper tridiagnonal system Ux=b using backward substitution.
(c) Function x=ltrisol(l,b) that solves the lower tridiagnonal system Lx=b using forward substituion. Solve above system of equations and check the answer.
