Up to this point tasks of interpolation for spline functions were discussed. Given are the points (xi,yi),i= 1, 2, … ,m, that can be understood as points of a functiony=g(x) that is to be described, but is otherwise unknown…...

csaps.CubicSmoothingSpline purports to perform extrapolation using the "natural" boundary condition. From https://github.com/espdev/csaps/blob/master/docs/formulation.rst: "csaps spline is cubic only and it has natural boundary condition type." This means the first derivative should be constant ou...
By using spline function theory in Hilbert space, we discuss the existence, uniqueness and characterization of the solution of the interpolation problem as well as its convergence. We show that the solution can be constructed in a simple way without using reproducing kernel semi-Hilbert space ...

self-affine in nature depending on the IFS parameters of univariate natural cubic spline CHFIFs. An upper bound of the error between the natural cubic spline blended coalescence fractal interpolant and the original function is deduced. Convergence of the natural cubic CHFIS to the original function...
A three dimensional STA (x, y and time) was sampled using 21 time samples. The spatial STA presented across all the figures was obtained as the 2 dimensional spatial slice at the maximum value after smoothing. The temporal STA is the one dimensional time slice at that same value. A double...
Model output was interpolated onto a regular 1 by 1 degree grid using the Climate Data Operator remapbil function44, and the calculated Atlantic stream function data interpolated onto common depth levels using the Python scipy RectBivariateSpline function. High and low sea ice years were defined as...
More copious data at the younger ages allowed for narrower smoothing windows. These empirical 5th, 25th, 50th, 75th and 95th percentiles were then modeled as a function of age. For the height-for-age curves, penalized cubic splines were used to estimate age-specific average height-percentile ...
