Question

Suppose I have a vector, say S=1:10, and a fixed number K=5. Is there a way to vectorize the following code?

v=zeros(1:10);

for i=1:10
    if S(i)>K
        v(i)=S(i)-K;
    else 
        v(i)=0;
    end
end

Answer 1

Just for educational purposes:

v = S - K;
v(v<=0) = 0;

Note that this gives you some flexibility, you can easily replace the final 0 by NaN or even remove all these entries by replacing it with []
