sum of an array and checking condition

Hi,

I have an array (1,10) which contains 10 values..now I have to sum the values of those array element and shall check whether the sum cross the limits or not. if it cross the limits then I need to know at which elements the conditions fails..

so if my array contains 2 2 2 1 2 2 1 2 2 2 then starting from my first elements of array, i shall sum up and shall check whether sum cross 6 or not..here at 4th element sum exceeds I need those index 4.

I tried but my logic jumbled up..

if v be your array having your values then

 for i=1:10
if (sum(v(1:i))>6)
i
break
end
end

it would show your desired value 4

thanks

 checksum = 0;
 I=0;
 while checksum<=limit
 I=I+1;
 checksum=checksum+yourarray(I);
 end

You can use cumsum function

v=[2 2 2 1 2 2 1 2 2 2];
idx=find(cumsum(v)>6,1)
