Use the BiConjugateGradientStabilizedSolverT class to solve large, non-symmetric sparse systems of equations using the Stabilized Bi-Conjugate Gradient method (BiCGStab). Convergence is more stable than the Conjugate Gradient Squared (CGS) method.

To solve a system of equations using this class, construct a new instance, passing the matrix of the system to the constructor. You can optionally set a preconditioner by setting the Preconditioner property. By default, a JacobiPreconditionerT is used. Finally, the Solve method solves the system.

Once the algorithm finished, the Status property indicates whether the algorithm completed successfully.
