Detailed Description

To compute a least square approximation.

This class enables using approximation methods to mathematically define a geometry.

The algorithms used in this class are largely inspired from the book: An Introduction to NURBS, by David F. Rogers. Copyright (C) 2000 David F. Rogers,
