/*! @brief Matrice_Morse_Diag class - Represents a sparse symmetric matrix M stored in Morse format.
 *
 *     Diagonal: 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_Sym.
