I have a question regarding the most efficient way to select a substring of
a vector:
I have a vector of value v, and I want to select a subspace of this vector
called w such that:
w=v[1:n]
where
sum(w) = x
I am interested in what you thing would be the most efficient way to do this
- I would like to avoid slowing down my simulations as much as possible.
Thank you very much for any help that anyone is able to give.
