provides cubic spline evaluations
- SPLINEV( coeff<, delta<, nout>>)
The SPLINEV function returns a two-column matrix containing the
points of evaluation in the first column and the corresponding
fitted values of the spline in the second column.
The inputs to the SPLINEV function are as follows:
- is an n ×5 (or n ×9) matrix of
spline coefficients, as returned by the SPLINEC Call.
The coeff argument should not contain missing values.
- is an optional vector specifying evaluation points.
If delta is a scalar, the spline will be
evaluated at equally spaced points delta apart.
If delta is a vector arranged in ascending
order, the spline will be evaluated at each of these values.
Evaluation at a point outside the support of the
spline results in a missing value in the output.
If you specify the delta argument,
you cannot specify the nout argument.
- is an optional scalar specifying
the number of fitted points desired.
The default is nout=200.
If you specify the nout argument, you
cannot specify the delta argument.
See the section "SPLINE and SPLINEC Calls" for details and examples.
