| Dear John,
| 
| I have the example.
| Make file:
| 
| function y=ff(x)
|         y= x^2;
| endfunction
| then call
| fmins( @ff, .1 )
| It will be fine.
| 
| But if you
| function y=ff(x)
|         y= x^2;
|       asdfasdf
| endfunction
| the calling of
| fmins( @ff, .1 )
| will return the same w/o any bug. You may alter the content of the function 
to realize
| a correct result but with different minima. The fmins will return the same 
result which makes
| me to believe that octave cached the function.

That's the problem.

I think this bug is fixed in the current development sources.  I don't
think there is a simple way to make this work in the 3.0.x sources, so
I don't expect it will be fixed in any 3.0.x release.
