Type Parameters

Remarks
Use the JacobiSolver<T> class to solve large, sparse systems of equations using the Jacobi method. This method is sometimes called the method of simultaneous displacements.
To solve a system of equations using this class, construct a new instance, passing the matrix of the system to the constructor. Finally, the Solve() method solves the system.
Preconditioners cannot be used with this method.
Once the algorithm finished, the Status property indicates whether the algorithm completed successfully.
