I'll start documenting as I'm going along.  Once I have a working draft I'll 
post it.  I just learned how to spell Levenberg Marquardt a few days ago, so 
I'll probably need some help filling in blanks.  Hope to have a rough draft 
soon.

Cheers,
- Ole

It would be great to have a nicely documented simple example to
include in the User Guide.  A patch or post containing such an example
would be greatly appreciated.

Thanks!

Hi,


Hi Ole,



I'm trying to fit a normal distribution to a curve (I'm assuming the
LM Optimizer is a good tool for this).  Is there a generic approach
that lets me construct a Jacobian or do I need specialized knowledge
of the function in order to do this?


There is a special packe for curve fitting in Apache Commons Math:
org.apache.commons.math.optimization.fitting. Since July 2010, this
package contains a dedicated GaussFitter classIn the subversion repository
(and hence in the upcoming 2.2 release). 
See.

best regards,
