Question

the question should be done on Matlab.

There is a vector defined as H = [-88, 45, 75, 24, 14, 19, -11, 9, -5, -3, 12, 19 ,56, -4, 5,

17, -6, -8, -9, 6, 15]

Write a program as a script file that triples the elements that are positive and a divisible by 3 or 5, and, raises to the power of 2 the elements that are negative but greater than -11.

Answer 1

Code:

H = [-88, 45, 75, 24, 14, 19, -11, 9, -5, -3, 12, 19 ,56,...
    -4, 5,17, -6, -8, -9, 6, 15];
n = size(H); % [ 1 x ] where x = no. of elements in H
n = n(2); % n= x

for i = 1:n % loop through elements of H
    if(H(i)>0) % if element is greater than 0
        % and divisible by 3 or 5 
        if((mod(H(i),3)==0)||(mod(H(i),5)==0))
            % then triple it
            H(i)=H(i)*3;
        end
    elseif(H(i)<0) % if element is less than 0
        % if greater than -11
        if(H(i)>-11)
            % raise it to the power of 2
            H(i)=2^(H(i));
        end
    end
end
disp(H);
