Hi everybody,

I would like some help here.

So I have a vector (C) that has 10 random numbers.

C = [ 2 5 4 3 6 7 3 4 2 1]. I would like to cumulatively sum the elements with the condition of the sums not exceeding 12 i.e 2+5+4 = 11 (under 12) then move to the next 3+6 = 9 (under 12) .. ans so on. Then storing the cumulaitve sums in a differnt vector G. So the results will be like: G = [11 9 10 7].

Thank you

Probably just the straightforward loop is the simplest here...

You could use cumsum and locate the position via find(cumsum(C)<12,1,'last') and then repeat again with the subsequent portion of the original vector, but I suspect just the straightahead sum will be quicker to code and probably faster.

No really unique solution pops to mind....not to say there isn't one.
