Detailed Description

template<class E>
class tvmet::AliasProxy< E >

Assign proxy for alias Matrices and Vectors.

A short lived object to provide simplified alias syntax. Only the friend function alias is allowed to create such a object. The proxy calls the appropriate member alias_xyz() which have to use temporaries to avoid overlapping memory regions.

Thanks to ublas-dev group, where the principle idea comes from.
