Spline is a software which is able to interpolate an Akima-spline through a series of given points. The interpolation approximates a manually drawn curve better than the ordinary splines, but the second derivation is not continuous.
Usage: aspline [-hv][-a [xstep]][-l llimit][-u ulimit][-n points] {data-file(s)}
-a, --auto supply abscissas automatically.
-l, --llimit set lower x-limit.
-u, --ulimit set upper x-limit.
-n, --points space output points so that approx. n intervals
occur between the lower and upper limit.
-h, --help display this help and exit.
-v, --verbose be verbose.
-V, --version display version and copyright information and exit.
-W, --warranty display licensing terms.
