Question

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

Explanation / Answer

Am sorry but, Chegg restricts us to answer 1question at a time, so am unable to answer question 5

Answers to question 4 are given below:

function result = answer4a(x)
n = numel(x); //find number of elements
    result = 0;
    for j=1:n %outer sum loop
        product = 1;
        for i=1:n %inner product loop
            if i == j
                continue;
            end
            product = product * x(i)^2 * exp(x(j));
        end
        result = result + product;
    end
end

function result = answer4b(x)
n = numel(x);
    result = 1;
    for j=1:n %outer product loop
        sum = 0;
        for i= 1 : n %inner sum loop
            if i == j
                continue;
            end
            sum = sum + sin(x(i)^2)*cos(x(j));
        end
        result = result * sum;
    end
end
