Stop Current Recording and Store Function Object

Syntax

d_fun

f = cppad_py::d_fun ( ax , ay )

a_fun

af = cppad_py::a_fun ( f )

ax

This argument has prototype

      const vec_a_double& ax

and must be the same as ax returned by the previous call to independent ; i.e., it must be the independent variable vector. We use the notation n = ax.size () to denote the number of independent variables.

ay

This argument has prototype

      const vec_a_double& ax

It specifies the dependent variables. We use the notation m = ay.size () to denote the number of dependent variables.

f

This result has prototype

      cppad_py::d_fun f

It has a representation for the floating point operations that mapped the independent variables ax to the dependent variables ay . This object computes function and derivative values using double .

Empty Function

In the case where ax and ay have size zero, the function is ‘empty’ and all its sizes are zero; see cpp_fun_property.

af

This result has prototype

      cppad_py::a_fun af

It has a representation of the same function as f . This object computes function and derivative values using a_double . Initially, there are not Taylor coefficient stored in af ; i.e., af_size_order() is zero.

Example

All of the examples use these constructors.
