public abstract class BasisHatShapeControl
extends TensionBasisHat

BasisHatShapeControl implements the shape control function for the hat basis set as laid out in the framework outlined in Koch and Lyche (1989), Koch and Lyche (1993), and Kvasov (2000) Papers. Currently BasisHatShapeControl implements the following shape control customizers:

• BasisHatShapeControl Constructor
• Retrieve the Type of the Shape Controller
• Cubic Polynomial with Rational Linear Shape Controller
• Cubic Polynomial with Rational Quadratic Shape Controller
• Cubic Polynomial with Rational Exponential Shape Controller
