NAME gr_spline - a GRToolbox module DESCRIPTION Splining 2 or 3D point data. Different parmetrizations can be chosen. All points must be distinct. SYNOPSIS: -[edge eps g n arc chord normx absx equih o v noc nof now skip f m c e i s l] -help For help on all options. Special Options: -g name File for the knots. (Default: equidistant knots) -n int Number of points to be splined. (Default: 100) -edge float Accuracy at edge. (Default: 0) -eps float Accuracy for taking known points. (Default: 0) Parametrization: -chord Using chordal parametrization, which is an approximation to the arclength. -arc Same as -chord. -normx Using (x[i+1]-x_[i])*(x[i+1]-x_[i]) as knots. -absx Using (x[i+1]-x_[i])*(x[i+1]-x_[i]) as knots. -equi Using equidistant spacing between as knots (Default).
