MATLAB: How to sum values of an array of variables, not the sum of the true/false values (0,1)

arrayflaseMATLABtruevariable

I'n very new to matlab! The code itself does work but and i've had to simplify it because it's for coursework, but i have a for loop with if and and else if inside it to meet some conditions
s=0;
for i=1:N;
  if 22==X(i) & 0<Y(i) & 2002==Z(i);
      s=s+1;
      else if  22==C(i) & 0<D(i) & 2002==Z(i);
      s=s+1;  
      end
  end
end
but the problem is that I think it changes the values to 0/1 according to whether it's true or not, but i want the actual sum of values of the goals (here it's Y and D)?

I’m not certain what you’re asking, and it’s difficult to follow your code, but if you want to add ‘Y(i)’ and ‘D(i)’ to ‘s’, do it explicitly:
s = s + Y(i);
or perhaps:
Ysum = Ysum + Y(i);
&c.
