Remarks
IterativeSparseSolver<T> serves as the abstract base class for classes that implement iterative solvers for sparse linear systems.
The only operation the matrix of the linear system must support is matrix-vector multiplication. All matrix types support this operation, but any object whose type inherits from LinearOperator will do.
IterativeSparseSolver<T> is an abstract base class and cannot be instantiated directly. Instead, use one of the derived classes:
To solve a system of equations, create a new instance of one of the classes above and pass the matrix or linear operator to the constructor. You can optionally set the Preconditioner property to a corresponding instance of one of the Preconditioner<T> classes. Finally, call the Solve() method to run the algorithm.
