So what i have is a feed in of an array (48x365) which is half hourly electricty cost data for each day. I need to get the time to start storing, over 6 hours which will be the minimum of 12 consecutive numbers in the array. Any ideas woud be great? > > > > so (48x365) need to find lowest sum of 12 consecutive numbers. > ------------------------------------------------------------------------------------------------------- > Did you look at all input and output arguments of the min() function? - - - - - - - - - - - - Call the 48 by 365 data array D. h = 12; C = [zeros(1,size(D,2));cumsum(D,1)]; S = min(C(h+1:end,:)-C(1:end-h,:)); S is a 1 by 365 row vector of the minimum sum for each column.
