This paper is concerned with the problem of existence of monotone and/or convex splines, having degree $n$ and order of continuity $k$, which interpolate to a set of ...

is a 1 ×2 matrix of endpoint values. Slopes of the two ends of the curve are reported as angles expressed in degrees. The SPLINEC call returns the endval argument. The inputs to the SPLINEC subroutine ...

A general setting is given for smooth interpolating splines depending on a parameter such that as this parameter approaches infinity the spline converges to the piecewise linear interpolant. The ...

We can see the difference between SVI and spline more clearly here. As expected, SVI curves show nice “smiles.” On the other hand, the spline follows the datapoints more closely but can go only as far ...
