EquationSolver()

public EquationSolver()

equals(Object arg0)

public boolean equals(Object arg0)

Parameters:

Parameter	Type	Description
arg0	java.lang.Object

Returns: boolean

getClass()

public final native Class<?> getClass()

Returns: java.lang.Class

hashCode()

public native int hashCode()

Returns: int

notify()

public final native void notify()

notifyAll()

public final native void notifyAll()

solve(double[][] matrix, double[][] rightSide)

public static double[][] solve(double[][] matrix, double[][] rightSide)

Returns the solution matrix if the matrix is square or the least squares solution otherwise. Formula = (A’ * A) ^ -1 * A’ * RS

---

// Create a matrix. Please note that this matrix
 // is singular (i.e. not invertible), so only a 
 // least squares solution would be feasible here.
 double[][] matrix = new double[][]
 {
   {1.0, 2.0, 3.0},
   {4.0, 5.0, 6.0},
  {7.0, 8.0, 9.0},
 };
 // Define a right side matrix b:
 double[][] rightSide = { {1}, {2}, {3} };
 // Solve the linear system Ax = b by finding x:
 double[,] x = Matrix.Solve(matrix, rightSide, leastSquares: true);
 // The answer should be { {-1/18}, {2/18}, {5/18} }.

Parameters:

Parameter	Type	Description
matrix	double[][]	The matrix for the linear problem.
rightSide	double[][]	The right side b .

Returns: double[][]
