User-Supplied Routines.
The purpose of each of the user-supplied routines in
the file xxx.f90,f is described below.
- -
- FUNC :
defines the function in (2.1), (2.2), or (2.3).
- -
- STPNT :
This routine is called only if IRS=0
(see Section 10.8.5 for IRS),
which typically is the case for the first run.
It defines a starting solution of (2.1) or (2.2).
The starting solution should not be a branch point.
(Demos ab, exp, frc, lor.)
- -
- BCND :
A routine BCND that defines the boundary conditions.
(Demo exp, kar.)
- -
- ICND :
A routine ICND that defines the integral conditions.
(Demos int, lin.)
- -
- FOPT :
A routine FOPT that defines the objective functional.
(Demos opt, ops.)
- -
- PVLS :
A routine PVLS for defining ``solution measures''.
(Demo pvl.)
In a C language equation file, these routines are written using
lowercase letters; with Fortran you can use any case.
