◆ Type

Enumeration defining the types of interpolation methods availables.

Passed as argument to instantiate mathlib::Interpolator objects. The types available are (more information is available in the GSL manual):

  • LINEAR interpolation;
  • POLYNOMIAL interpolation, to be used for small number of points since introduces large oscillations;
  • CSPLINE cubic spline with natural boundary conditions;
  • CSPLINE_PERIODIC cubic spline with periodic boundary conditions;
  • AKIMA, Akima spline with natural boundary conditions ( requires a minimum of 5 points);
  • AKIMA_PERIODIC, Akima spline with periodic boundaries ( requires a minimum of 5 points);
