The following options are recognized, each as a separate argument.
5 -a Supply abscissas automatically (they are missing from the input); spacing is given by the next argument, or is assumed to be 1 if next argument is not a number.
5 -k The constant k "" used in the boundary value computation

is set by the next argument. By default k "" = 0.
5 -n Space output points so that approximately n intervals occur between the lower and upper x limits. (Default n = 100.)
5 -p Make output periodic, i.e. match derivatives at ends. First and last input values should normally agree.
5 -x Next 1 (or 2) arguments are lower (and upper) x limits. Normally these limits are calculated from the data. Automatic abcissas start at lower limit (default 0).
