When doing


fminsearch(@sin, 0)
pkg load optim
fminsearch(@sin, 0)


one gets the interesting result

----
ans = -1.57
error: Invalid call to optimget.  Correct usage is:

 -- Function File:  optimget (OPTIONS, PARNAME)
 -- Function File:  optimget (OPTIONS, PARNAME, DEFAULT)
 
error: called from:

line 77, column 10
error:   /usr/local/octave-dev/share/octave/packages/optim-1.2.2/fminsearch.m
at line 33, column 6

Note the two different calls to fminsearch without ever changing the path.
