Hi there 

First of all congratulations,  I like this a lot and it works really well for what I wanted, and is nice and easy to use.   

I have plugged your library together with the Math.NET numerics libaries and got Levenberg Marqardt working in a test harness.  

so some suggestions are

1  a string parser to allow user defined functions to be submitted and compiled 

2 Make use of Math.net library functionality for matrices etc they have done a lot of work on solvers etc

Hi

Thanks for the feedback. I'm still working on making it faster and being able to handle larger problems and functions with sparse derivative structures. I'm almost ready with a forward-mode version, also with support for compiled expressions.

1. That's a good point.

2. I'll have a look at Math.NET, looks promising. I'm not really using much matrix algebra, though, that's mostly done in the external Ipopt optimizer.
