Class Scine::Utils::AutomaticDifferentiation::Second3D¶
-
class
Second3D¶ Class representing values in three dimensions and allowing for the automatic calculation of first and second derivatives.
Public Functions
-
Second3D()¶ Constructor that takes no arguments and intializes value and derivatives to Zero.
-
Second3D(double v, double dx, double dy, double dz, double xx = 0, double yy = 0, double zz = 0, double xy = 0, double xz = 0, double yz = 0)¶ Constructor that takes the value and all derivatives as doubles.

double
value() const¶ Getter for the value.
- Return
double Value.
-
void
setValue(double v)¶ Setter for the value.
-
void
