a_double_ctor

Headings-> Syntax Purpose d a_other ad Example

@(@\newcommand{\B}[1]{ {\bf #1} } \newcommand{\R}[1]{ {\rm #1} }@)@The a_double Constructor
Syntax
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 preform algorithmic differentiation.

d
This argument has prototype
     const double& d
The resulting ad variable represents a constant function equal to d .

a_other
This argument has 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.
