Class Scine::Utils::AutomaticDifferentiation::FirstND

class FirstND : public Scine::Utils::AutomaticDifferentiation::FirstBase<Eigen::MatrixXd, FirstND>

Class representing values in N dimensions and allowing for the automatic calculation of first derivatives in those N dimensions.

Public Functions

FirstND(double v, Eigen::MatrixXd d)

Constructor that takes the value of the function as a double and the derivatives as an Eigen::MatrixXd.

int dimensions() const

Getter for the number of dimensions of the function.

Return

int Number of dimensions.

double derivative(int index) const

Getter for the derivative.

Return

double

Parameters

• int: Index to the derivative that should be returned in the N dimensional derivatives object.
