Member Function Documentation
◆ GetDer()
|
inlineoverridevirtual |
Return the first derivative of the function.
Default implementation computes a numerical differentiation. Inherited classes may override this method with a more efficient implementation (e.g. analytical solution).
Reimplemented from chrono::ChFunction.
◆ GetDer2()
|
inlineoverridevirtual |
Return the second derivative of the function.
Default implementation computes a numerical differentiation. Inherited classes may override this method with a more efficient implementation (e.g. analytical solution).
Reimplemented from chrono::ChFunction.
◆ GetVal()
|
inlineoverridevirtual |
Return the function output for input x.
Must be overridden by specialized classes.
Implements chrono::ChFunction.
