couldn't the diagonal matrix class be extended to have a variable that holds the value of the non-diagonal elements of the matrix? Usually this would be zero, but when the matrix is multiplied with NaN or divided with zero, this value would change.
That is what I meant by "default sparse value", or value V0 in the set of Omega-(IJ1+IJ2+IJ3+...+IJN) -> V0 i.e., the most prevalent value in the matrix. Dan
