Detailed Description

template<class Type, class DType, class LUType>
class Foam::LduMatrix< Type, DType, LUType >

LduMatrix is a general matrix class in which the coefficients are stored as three arrays, one for the upper triangle, one for the lower triangle and a third for the diagonal.

Addressing arrays must be supplied for the upper and lower triangles.

Note: It might be better if this class were organised as a hierarchy starting from an empty matrix, then deriving diagonal, symmetric and asymmetric matrices.
