How to take integral with for loop?

Hello,

I would like to integrate my function with for loop.

for l = 1: length(x)-1

final(l) = (upper(i+1)-upper(i)).*(w(2)-w(1)) ;

end

where x is my function and l is my time. i cannot have desired output. how can i do that?

Add the command

I = sum(final);

after the loop.
