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.

Currently I am using octave-3.0.1 stable with Ubuntu.
