## Definition

The concept `Function` represents a function.

See Also
  `FunctionKernel`
  `FunctionKernel::ConstructFunction`

Example

Several ways to create functions:

Using `Kinetic::ConstructFunction`:

Traits::Function_kernel::Construct_function cf= traits.function_kernel_object().construct_function_object();
Traits::Kinetic_kernel::Motion_function x= cf(0.0,1.0,2.0);
Traits::Kinetic_kernel::Motion_function y= cf(0.0,1.0,2.0);
Traits::Kinetic_kernel::Point_2 pt(x,y);

Using the constructor:

double coefs[]={1.0, 2.0, 3.0};
Traits::Kinetic_kernel::Motion_function z(coefs, coefs+3);

Using ring operations:

Traits::Kinetic_kernel::Motion_function z= x*z+y;

## Types

typedef unspecified_type | NT
| The number type used in describing the function.
| Function (NT)
| Construct a constant function from a number.

## Operations

NT | operator() (NT)
| Evaluate the function at an `NT`.
