Consider the following 3D function: f(x, x, x3) = 4x + 2xx

Consider the following 3D function: f(x, x, x3) = 4x + 2xx + 3x + x x3 + 2x + 5x +3 Find the stationary point x that satisfies Vf(x) = 0. Requirements: a) Derive the equations that satisfy Vf = 0, rewrite the equations in the matrix-vector product format, and report the equations on papers (50%) b) Write Matlab codes to solve the above equations using the Gauss-Seidel method. Use x = (1,1,1) as the initial guess and perform 10 Gauss-Seidel iterations. Report the final solution x* at the 10th iteration and the initial and final residual norms on papers. Upload your Matlab code to Canvas. (50%)
