The body of the curve, the part between braces, takes various forms:
- a sequence of explicit breakpoint specifying the value of the function
at the breakpoints and the interpolation type between breakpoints (as
exemplified previously);
- sequence of symbolic breakpoints where the interval bteween
breakpoints, the value at each breakpoints and the intrepolation type is
not precisely given (only a general pace: increasing, decreasing,
etc. is specified);
- a [nim] which is value that represents a function (this value can be
computed elsewhere);
- a set of differential equations (this experimental feature is
described in the next chapter).
Even if the specification of the body takes several forms, the principe
of the curve is the same: the idea is to sample in time a function
defined through a way or another.
