Detailed Description

Matrice_Morse_Sym class - Represents a sparse symmetric matrix M stored in Morse format.

Symmetric: only the upper triangular part of the matrix is stored. Important: All diagonal coefficients must be stored even if they are zero (TRUST assumption for several methods including multvect). This class derives from Matrice_Morse and Matrice_Sym.

Matrice_Morse_Sym operator* ( const Matrice_Morse_Sym & A, double x )

friend

Friend function (non-member) of class Matrice_Morse_Sym. Simply calls operator*(double,const Matrice_Morse_Sym&) (which is NOT IMPLEMENTED).

Parameters

(Matrice_Morse_Sym&	A) the matrix to multiply by x
(double	x) a scalar

Returns

(Matrice_Morse_Sym) the result of the underlying call
