SplineClass Class Reference

Detailed Description

A spline is a curve given by the form y = ax^3 + bx^2 + c*x + d As there are 4 constants, 4 constraints are needed to create the spline. These constraints could be the derivative or value at a point Often, the value and derivative of the value are known at two points.
