Enumeration defining the smoothness of table interpolation

Literals

NameDescription
LinearSegmentsLinear interpolation
ContinuousDerivativeAkima spline interpolation (such that the first derivative is continuous)
ConstantSegmentsPiecewise constant interpolation (the value from the previous abscissa point is returned)
MonotoneContinuousDerivative1Fritsch-Butland spline interpolation (such that the monotonicity is preserved and the first derivative is continuous)
MonotoneContinuousDerivative2Steffen spline interpolation (such that the monotonicity is preserved and the first derivative is continuous)
ModifiedContinuousDerivativeModified Akima spline interpolation (such that the first derivative is continuous and shortcomings of the original Akima method are avoided)
NaturalCubicSplineCubic spline interpolation with natural boundary conditions (such that the first and second derivatives are continuous)
