Constructor Details

EquationSolverImpl

public EquationSolverImpl()
                   throws RemoteException

Creates a new EquationSolverImpl. Invokes UnicastRemoteObject's constructor to register this object with the RMI runtime.

Throws:

RemoteException

Method Details

solve

public double[] solve(double[][] matrix,
 double[] constants)
               throws RemoteException

Use Cholesky's algorithm to solve a linear system of equations of the Ax = b.

Specified by:

solve in interface EquationSolver

Parameters:

matrix - The A in Ax = b

constants - The b in Ax = b

Throws:

IllegalArgumentException - The number of rows and columns in the matrix are not the same

RemoteException - Something went wrong while communicating with the server

main

public static void main(String[] args)

Main program that creates a new EquationSolverImpl and binds it into the RMI registry under a given name.
