Detailed Description

template<typename TRing, typename TAlloc>
class DGtal::MPolynomial< 0, TRing, TAlloc >

Aim: Specialization of MPolynomial for degree 0.

Description of template class 'MPolynomial'

Stores a polynomial of degree 0, i.e. a scalar of type T. We assume that the type T is not "too" complex, otherwise this class will be partially not very effective.

Template Parameters

TRing	the type chosen for the polynomial, defines also the type of the coefficents (generally int, float or double).
TAlloc	is an allocator for TRing, for example std::allocator<TRing>; this is also the default parameter. Usually this parameter does not needs to be changed.

This class is a backport from Spielwiese.
