Write a Matlab code implementing the function which gets as an argument a vector of scalar values X = [xi] for i = 0, 1, 2, .., n, which returns as a result the value of the expression: Group A: v = Sigma^n_i = 0 (Product^n_j = 0, j notequalto 1 x^2_i e^xj) Group B: z = Product^n_j = 0 (Sigma^n_i = 0, j notequalto sin(x^2_i) cos(x_j)). Write a Matlab code implementing the program which will calculate the value of the given integral using composite Simpsons rule with 9 subintervals (10 evaluation points of the integrated function): Group A I = integral^3_-1 e^-2t^2 sin(t) dt Group B: I = integral^3_0 -e^(t^-1) cos(t) dt
