A command to transform the selected Polynomial object to a new domain.
The polynomial is transformed from domain [xmin, xmax] to domain [Xmin, Xmax] in such a way that its form stays the same. This is accomplished by first calculating:
|f(x′) = Σk=1..numberOfCoefficients ck x′k, where|
|x′ = a x + b,|
and then collecting terms of equal degree. The a and b are defined as
|a = (xmin – xmax) / (Xmin – Xmax)|
|b = xmin – a Xmin|
