IterInverse - Provide an iterative inverse transformation?

Description:

This attribute indicates whether the inverse transformation of the PolyMap should be implemented via an iterative Newton-Raphson approximation that uses the forward transformation to transform candidate input positions until an output position is found which is close to the required output position. By default, an iterative inverse is provided if, and only if, no inverse polynomial was supplied when the PolyMap was constructed.

The NiterInverse and TolInverse attributes provide parameters that control the behaviour of the inverse approcimation method.

Type:

Integer (boolean).

Class Applicability:

PolyMap

All PolyMaps have this attribute.

Notes:

• An iterative inverse can only be used if the PolyMap has equal numbers of inputs and outputs, as given by the Nin and Nout attributes. An error will be reported if IterInverse is set non-zero for a PolyMap that does not meet this requirement.
