GEN08 — Generate a piecewise cubic spline curve.
This subroutine will generate a piecewise cubic spline curve, the smoothest possible through all specified points.
size  number of points in the table. Must be a power of 2 or powerof2 plus 1 (see f statement).
a, b, c, etc.  ordinate values of the function.
n1, n2, n3 ...  length of each segment measured in stored values. May not be zero, but may be fractional. A particular segment may or may not actually store any values; stored values will be generated at integral points from the beginning of the function. The sum n1 + n2 + ... will normally equal size for fully specified functions.
Note  


Here is an example of the GEN08 routine. It uses the files gen08.csd.
