## Definition

Given a constant \( c\) this `AdaptableBinaryFunction` scales a `PolynomialTraits_d::Polynomial_d` \( p\) with respect to one variable, that is, it computes \( p(c\cdot x)\).

Note that this functor operates on the polynomial in the univariate view, that is, the polynomial is considered as a univariate polynomial in one specific variable.

## Types
typedef PolynomialTraits_d::Polynomial_d | result_type
typedef PolynomialTraits_d::Polynomial_d | first_argument_type
typedef PolynomialTraits_d::Innermost_coefficient_type | second_argument_type

## Operations
result_type | operator() (first_argument_type p, second_argument_type c)
| Returns \( p(c\cdot x)\), with respect to the outermost variable.
result_type | operator() (first_argument_type p, second_argument_type c, int i)
| Same as first operator but for variable \( x_i\).

## ◆ operator()()

result_type PolynomialTraits_d::Scale::operator() | ( | first_argument_type | p,
|  | second_argument_type | c,
|  | int | i
| ) |  |

Same as first operator but for variable \( x_i\).

Precondition
  \( 0 \leq i < d\).
