Linear equation solving method for rare matrices.

Hi All !!!

Can anyone give me link to the C++ source or to the compiled program unit
(compatible with Microsoft VC++), designed for the solving of the algebraic
linear systems with rare matrices ? The main problem is next: the main rare
matrix of the system is in the common form, but not in the special (non
triangular, non symmetric, ...). That's why many methods for such systems is
unusual.

Because of being rare, matrix can be huge, and in such cases "Out of memory
error" occurs. We have immediate huge task to solve, that's why I haven't
time to develop my own method, my own module.

It can be unit with own datatypes to decrease amount of used memory or even
"closed-box" unit, whith uses input matrix, stored on the HDD.

Thank you.

Maybe this could help you:

Another commercial option could be NAG C Library
