§Higher level Interface

§Implemented GSL features

  • 1D Interpolation
    • Instantiation [gsl_interp_alloc(), gsl_interp_init(), gsl_interp_free()]
    • 1D Interpolation types [gsl_interp_type]
      • Linear [gsl_interp_linear]
      • Polynomial [gsl_interp_polynomial] 1
      • Cubic [gsl_interp_cspline]
      • Cubic Periodic [gsl_interp_cspline_periodic] only works for 3 points at the moment; the general case is missing a cyclically tridiagonal matrix solver, which is currently not implemented by ndarray_linalg.
      • Akima [gsl_interp_akima], could use some better testing
      • Akima Periodic [gsl_interp_akima_periodic]
      • Steffen [gsl_interp_steffen]
    • Evaluation 2
      • f(x) evaluation [gsl_interp_eval()]
      • f’(x) evaluation [gsl_interp_eval_deriv()]
      • f’’(x) evaluation [gsl_interp_eval_deriv2()]
      • Numerical Integral [gsl_interp_integ()]
    • Utility functions
      • Name [gsl_interp_name()]
      • Minimum number of points [gsl_interp_min_size() and gsl_interp_type_min_size()]
    • Higher level Interface (Splines)
  • 2D Interpolation
    • Instantiation [gsl_interp2d_alloc(), gsl_interp2d_init(), gsl_interp2d_free()]
    • 2D Interpolation Grids [gsl_interp2d_set, gsl_interp2d_get(), gsl_interp2d_idx]
    • 2D Interpolation types [gsl_interp2d_type]
      • Bilinear [gsl_interp2d_bilinear]
      • Bicubic [gsl_interp2d_bicubic]
    • Utility functions
      • Name [gsl_interp2d_name()]
      • Minimum number of points [gsl_interp2d_min_size() and gsl_interp2d_type_min_size()]
    • Evaluation 2
      • f(x, y) evaluation [gsl_interp2d_eval()]
      • f(x, y) extrapolated evaluation [gsl_interp2d_eval_extrap()]
      • fx(x, y) evaluation [gsl_interp2d_eval_deriv_x()]
      • fy(x, y) evaluation [gsl_interp2d_eval_deriv_y()]
      • fxx(x, y) evaluation [gsl_interp2d_eval_deriv_xx()]
      • fyy(x, y) evaluation [gsl_interp2d_eval_deriv_yy()]
      • fxy(x, y) evaluation [gsl_interp2d_eval_deriv_xy()]
    • Higher level Interface (Splines)
  • Acceleration
    • Instantiation [gsl_interp_accel_alloc(), gsl_interp_accel_reset(), gsl_interp_accel_free()]
    • Lookup [gsl_interp_bsearch(), gsl_interp_accel_find()]

  1. Polynomial Interpolation is probably not going to be implemented, since it relies on divided differences and after all, it is a terrible interpolation method. ↩

  2. _e() evaluation functions are probably not gonna be implemented. ↩ 1 2
