Hi,

I think that the advantages of a one-file/multiple-functions are
obvious. Humm... simpler to maintain, at least. And more elegant, for
sure!

And it would be enough to add to Octave a procedure to register other
existing functions in the file.

E.g., a minmax.cc function should contain:

  DEFUN_DLD (min, args, nargout,
  ...
  DEFUN_DLD (max, args, nargout,
  ...
  DEFUN_DLD (minmax, args, nargout,
    // register max() and min() as existing in this file
    REGFUN("max");
    REGFUN("min");
  ...

and should be named minmax.oct.

Of course this implies explicit user initialization, that could be left
in ".octaverc". No free lunch! But compatible.

Arghh! "touché"

Perhaps not. And I think that this has been already addressed in this
mailing list.

If my multi-function file has to keep an internal global state variable,
"static int state", e.g., with file linking the "state" variable will be
local to each linked file/function, not global to all defined functions.
For simple variables, one could use "set/get_global_value", but for
complex structures...
