Sum up parts of a vector?

Dear all,
I have a 105120*1 vector and I want to sum up in steps of 288. So I want to have the sum of the first 288 elements, then the sum of the next 288 elements and so, until the end of the vector. So finally I want to have a new vector of the dimension 365*1. So I need finally 365 sums. How can I do that?

Something like
k = 1;
stepsize = 288;
for nn = 1:288:105210-stepsize
partsum(k) = sum(vekt(nn:nn+stepsize-1));
k = k+1;
end
That's one possible way. There are many others.
