Detailed Description

template<class T>
class triplet< T >

Verbose description of a matrix element.

A triplet consists of row and column indices in a matrix together with the value of the corresponding matrix cell. As the full position information is part of the object, a triplet can describe a matrix element all by itself, and an unordered collection of triplets with unique addresses can describe all nonzero entries of a matrix.
