The a_double Constructor

Syntax

C++

cppad_py::a_double ad ()

cppad_py::a_double ad ( d )

cppad_py::a_double ad ( a_other )

Python

ad = cppad_py.a_double ()

ad = cppad_py.a_double ( d )

ad = cppad_py.a_double ( a_other )

Purpose

Creates a cppad_py::a_double object that can be use to track floating point operations and perform algorithmic differentiation.

d

This argument has c++ prototype

      const double& d

The resulting ad variable represents a constant function equal to d .

a_other

This argument has c++ prototype

      const a_double& a_other

The resulting ad variable is the same function of the independent variables as a_other .

ad

is the a_double object that is constructed.

Example

All of the other a_double examples use an a_double constructor.
