write a function to solve the system Ax=b where A is a positive definite matrix using the functions forward_subs, back_subs, and cholesky_factor

def solve_system (A, b, nargout-l): x = np. zeros (b. Shape) Replace this comment with code - write a function to solve the system Ax-b, where A is a positive definite matrix - use the functions forward_subs, back_subs, and cholesky_ factor - the function should return the solution vector x - The function should work for square matrices of any size return (x)
