Detailed Description

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.

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