Detailed Description

template<int N, class T0>
class esso::Ix< N, T0 >

Represents a small, fast vector.

Use this object for small vectors where the length of the vector is known at compile time. (It is possible to use it for larger datasets too, but it should be noted that all data is allocated on the stack, no dynamic memory is allocated by these objects).
