RE: Fmins

[Heber Farnsworth]

There is a function called nmsmax which uses the same algorithm as fmins but
maximizes rather than minimizes.  It is not part of Octave.  You can get it
from the Mathworks anonymous ftp site at

ftp://ftp.mathworks.com/pub/contrib/v4/optim/dsmax

More recent versions can be obtained from the authors web site as part of a
toolbox he calls the test matrix toolbox.  The web page is

http://www.ma.man.ac.uk/~higham/testmat.html

The only way in which you would need to change your code is to have nmsmax
maximize -f(x) where f(x) is the function you want to minimize.  Last time I
checked there was also some problem with the ^ versus ~ operator used in
that code.  Running octave with the --braindead option should take care of
it.  Alternatively you can edit the code and change the one instance of the
matlab operator to the octave one.
