natural_quintic_spline_noderiv R Documentation
Estimate natural quintic spline with unknown first derivatives
Description
Estimate a natural quintic spline from known values of the
function only. That is, it estimates the first and second derivatives at
each point by ensuring that the third and fourth derivatives are
continuous at each knot, and equal to zero at the first and the last point.
Usage
natural_quintic_spline_noderiv(xk, yk)
Arguments
xk
A vector of interpolation points.
yk
A vector of values at each interpolation point.
Value
A list with two components:
sk A vector of first derivatives at each point.
ak A vector of second derivatives at each point.
