I have this 2D array L(i,j). How can I sum all the elements depending of i
and make the result as a function of j
I did :
do j=1,10
do i =1,30
T(j) = Sum( L(:,j)
end do
end do
Is that ok?
Almost... you don't use i
(and you don't need to), and you are missing one bracket:
do j=1,10
T(j) = Sum( L(:,j) )
enddo ! j
You could also use the dimension parameter in sum
to do this operation in one line:
T = sum( L, dim=1 )
However, I find that very difficult to read and would stick with the loop - it shouldn't make a difference in terms of performance.
