Knot Vector

Key Knot Vector in Bond Curve Fit Method refers to the knots required by the CubicB spline algorithm.
For example, a set of knots may be:
-30.0, -20.0, 0.0, 5.0, 10.0, 15.0, 20.0, 25.0, 30.0, 40.0, 50.0
A cubic bspline curve with 11 knot points, implies n=6 (constrained problem) basis functions.
At least 8 knots are required.
