spline

spline <dset0> [<dset1> ...] [out <outfile>] [meshsize <n> | meshfactor <x>] [meshmin <mmin>] [meshmax <mmax>]

<dsetX> Data set(s) to perform splining on.
[out <outfile>] Write splined data to <outfile>.
[meshsize<n>] Size of the mesh to use for splining.
[meshfactor <x>] If meshsize is not given, use a mesh of data set size * <x>.
[meshmin <mmin>] Mesh X minimum value.
[meshmax <mmax>] Mesh X maximum value.

Cubic spline the given data sets.
