\ccDefinition
|
|
|
|
This \ccc{AdaptableUnaryFunction} inverts on variable in a given
|
|
\ccc{PolynomialTraits_d::Polynomial_d}.
|
|
|
|
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.
|
|
|
|
This functor is provided for efficiency reasons, since this operation just inverts the
|
|
order of the coefficients with respect to the specified variable.
