/** Interface defining an arbitrary bijective mapping from R^2 to R^2.<p>
|
|
|
|
This interface provides methods to define an arbitrary bijective
|
|
mapping from R^2 to R^2, i.e. from the two-dimensional space of
|
|
real numbers onto itself, as is representable by the
|
|
double floating point type. The mapping must be
|
|
bijective, i.e. map a pair of real numbers to exactly one other
|
|
pair of real numbers and vice versa, to facilitate a working
|
|
inverse. Bijectiveness also implies completeness, i.e. for every
|
|
pair of real numbers there must be another pair that is mapped
|
|
upon them.<p>
