Member Function Documentation
◆ Estimate_x_range()
|
overridevirtual |
Return an estimate of the range of the function argument.
(Can be used for automatic zooming in a GUI)
Reimplemented from chrono::ChFunction.
◆ Get_y_dx()
|
overridevirtual |
Return the dy/dx derivative of the function, at position x.
Note that inherited classes may also avoid overriding this method, because this base method already provide a general-purpose numerical differentiation to get dy/dx only from the Get_y() function. (however, if the analytical derivative is known, it may better to implement a custom method).
Reimplemented from chrono::ChFunction.
◆ Get_y_dxdx()
|
overridevirtual |
Return the ddy/dxdx double derivative of the function, at position x.
Note that inherited classes may also avoid overriding this method, because this base method already provide a general-purpose numerical differentiation to get ddy/dxdx only from the Get_y() function. (however, if the analytical derivative is known, it may be better to implement a custom method).
Reimplemented from chrono::ChFunction.
