Remarks

Use the ConjugateGradientSquaredSolver class to solve large, non-symmetric sparse systems of equations using the Conjugate Gradient Squared (CGS) method. Convergence can sometimes be erratic, and may sometimes break down completely.

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 JacobiPreconditioner is used. Finally, the Solve(Vector) method solves the system.

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