This package contains *.sci and *.m files for curve interpolation using natural splines. The *.sci files are for use with SciLab, the *.m files for use with GNU Octave.
This package uses a BSD style license, see FAQ. If SciLab and/or GNU Octave authors want to bundle these files with their software I'm willing to add additional licenses for that purpose.
The image beside shows some specified curve points (i.e. from measurements)
and the natural spline curve interpolation created by nsplines.
The GnuPlot program was used to draw the points and the curve.
