Detailed Description

Class to create jacobian functions.

This class can be used to create Jacobian function class types. Objects derived from this class are function objects, that map vector to matrix objects.

The Jacobian function objects must be initialized with a $ R^n \to R^m $ function, which must be provided in a QVFunction object. The Jacobian object function will use the method qvEstimateJacobian to obtain a numerical approximation of the Jacobian matrix for that vector function.

An example usage of these objects is the following:

class ExampleVectorFunction: public QVFunction<QVVector, QVVector>
                QVVector evaluate(const QVVector &v) const


int main()
        ExampleVectorFunction f;
        QVJacobian eJacobian(f);

        QVVector x = QVVector::random(10);
        std::cout << "x = " << x << std::endl;
        std::cout << "f(x) = " << f(x) << std::endl;
        std::cout << "Jacobian of f(x) = " << eJacobian(x) << std::endl;
