Hello,
I have a 16 x 24 matrix A composed of one row of the hours 0,1,2…23 (the first row), and in the rest of the rows, I have hourly wind powers, in which each row corresponds to the wind speeds in a different location in the world.
What I am trying to do is use matrix B of size 15 x 2 to specify start and end times in matrix A in a loop, and then add up the wind powers in each row between those times, inclusive, and then store each of those sums as an entry in a 15 x 1 matrix. Each row of B has different start and end times.
I will illustrate with a example:
A = [0 1 2 3 4 5... 5 6 7 8 9 2...]B = [0 3];size(A) = 2 x 5;size(B) = 1 x 2;
So I want to add up 5, 6, 7, and 8 to get 26, and store that value in a new column matrix. I want to do this for each row of A and B, but for different start and end values, depending on the row of B.
What I've done so far is this:
%%G is equivalent to matrix A above; Rounded_Bounds_WS is equivalent to matrix B above; J is the column matrix I'd like to create.
for s=1:length(files) %files is just the collection of .nc files I'm using (15)
if and(G(1,:)>= Rounded_Bounds_WS(s,1), G(1,:)<= Rounded_Bounds_WS(s,2)) J(s,:)=sum(G(s+1,:)); endend
But I haven't been able to get this to work. s cycles from 1 to 15 (where 15 =length(files); however the matrix J isn't even created.
Thank you in advance for your help.
Andrew
