Detailed Description

A tensor of degree 2 over an abstract vector space (volatile version).

Definition at line 43 of file t2.h.

Member Enumeration Documentation

static_const_int

enum fiber_bundle::t2_lite::static_const_int

The tensor degree (static version)

Hack:

Inline initialization of static const integral data members causes link error in MSC++; use enum instead.
