It is the most general version of any subvectors because it uses another vector of indices to reference the subvector.
The vector of indices can be of any type with the restriction that its elements must be type-compatible with the size_type of the container. In practice, the following are good candidates:
boost::numeric::ublas::indirect_array<A> where A can be int, size_t, long, etc...std::vector<A> where A can int, size_t, long, etc...boost::numeric::ublas::vector<int> can work too (int can be replaced by another integer type)An indirect vector can be used as a normal vector in any expression. If the specified indirect vector falls outside that of the indices of the vector, then the vector_indirect is not a well formed Vector Expression and access to an element outside of indices of the vector is undefined.
