Hello , im having a little trouble with a script to find a number of positive integers in a vector inputed by user without using loop comands. (have to do it for the uni) i know it should be simple but i cant figure it out. any help?
for example if input vector is v=[1 5 6 1.4 -4 0.5] then the number n should be 3.
