How to eliminate the for loop but end with the same result

A = input('Using brackets, enter a vector: ')

for i=1:length(A)

if(A(i) > 0)

B(i) = A(i).^3;

else

B(i) = 0;

end

end

B

How can I convert this code so that when the for loop and if statement are deleted the code still has the same output?

Try something like this —

A = -3:3;
B = A.^3.*(A>0)

B = 1×7

0 0 0 0 1 8 27

It uses a version of ‘logical indexing’.
