Method Detail

getJacobian

public Matrix getJacobian(VectorG at)

Gets the Jacobian matrix of this vector differentiable. The matrix returned is a QuadMatrix if VectorFunction.argumentDimension() = VectorFunction.functionDimension().

getJacobian

public static Matrix getJacobian(VectorDifferentiable f,
                                 VectorG at)

Gets the Jacobian matrix of this vector differentiable. The matrix returned is a QuadMatrix if VectorFunction.argumentDimension() = VectorFunction.functionDimension(). It is constructed of VectorFunction.functionDimension() rows, each VectorFunction.argumentDimension() wide.
