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 ...

SIAM Journal on Numerical Analysis, Vol. 8, No. 1 (Mar., 1971), pp. 67-74 (8 pages) It is shown that if x ∈ C4[a, b] is approximated by a natural cubic spline, then ...

The recent release of the rcssci R package represents a significant advancement in the way researchers visualize and analyze complex relationships between continuous variables and their outcomes. The ...

This example illustrates some properties of splines. Splines are curves, which are usually required to be continuous and smooth. Splines are usually defined as piecewise polynomials of degree n with ...
