class SimTK::Function_< T >::Constant
This is a Function_ subclass which simply returns a fixed value, independent of its arguments.
Calculate the value of this function at a particular point.
- Parameters
-
x | the Vector of input arguments. Its size must equal the value returned by getArgumentSize(). |
Implements SimTK::Function_< T >.
Calculate a partial derivative of this function at a particular point.
Which derivative to take is specified by listing the input components with which to take it. For example, if derivComponents=={0}, that indicates a first derivative with respective to component 0. If derivComponents=={0, 0, 0}, that indicates a third derivative with respective to component 0. If derivComponents=={4, 7}, that indicates a partial second derivative with respect to components 4 and 7.
- Parameters
-
derivComponents | The input components with respect to which the derivative should be taken. Its size must be less than or equal to the value returned by getMaxDerivativeOrder(). |
x | The Vector of input arguments. Its size must equal the value returned by getArgumentSize(). |
- Returns
- The value of the selected derivative, which is of type T.
Implements SimTK::Function_< T >.
