Question

can anyone help me solve these on MATLAB?? please

3. 50 points - The purpose of this question is to test your ability to write for loops, so you won't get points if your answer works without using for loop. A vector is given by V - (5. 17. -3,8,0,-7. 12, 15, 20. -6, 6, 4.-7.16). Write a program as a script file that doubles the elements that are positive and raise to the power of 3 the elements that are negative using for loop.

Answer 1

clear all;
clc;

V       = [5 17 -3 8 0 -7 12 15 20 -6 6 4 -7 16];
V_ans   = zeros(1,numel(V));

for i = 1:numel(V)
    if V(i) > 0
        V_ans(i) = 2*V(i);
    elseif V(i) < 0
        V_ans(i) = V(i)^3;
    end
end
