Dear May,
There are functions for fitting in the book Numerical Recipes
http://www.nr.com/.
A while ago, I had the same problem to fit some data in C++ and to
reproduce
the results from the Mathematica fit routine. The routine mrqmin
(implementation of the
Levenberg-Marquardt algorithm) should do what you want. The same
algorithm is also
normally used by default in Mathematica. At least, in my case the
results in C++ finally
were the same as in Mathematica.
Best regards,
Heiko
