Enum CubicInterpolationBoundaryCondition
A boundary condition of a Spline cubic interpolation, on its left
or right end: QuantLib's CubicInterpolation::BoundaryCondition, with its values. The local schemes ignore it.
public enum CubicInterpolationBoundaryCondition
Fields
FirstDerivative = 1Match the value of the end slope.
Lagrange = 4Match the end slope to the slope of the cubic that matches the first (or last) four data; at least 4 points.
NotAKnot = 0Make the second (or second-to-last) point an inactive knot; the condition's value is ignored.
Periodic = 3Match the first and second derivatives at either end; not implemented in QuantLib.
SecondDerivative = 2Match the value of the second derivative at the end.
