Description : Robust non-linear least squares curve fitting for GDL
These GDL routines provide a robust and relatively fast way to perform
least-squares curve and surface fitting. The algorithms are translated from
MINPACK-1, which is a rugged minimization routine found on Netlib, and
distributed with permission. This algorithm is more desirable than CURVEFIT
because it is generally more stable and less likely to crash than the
brute-force approach taken by CURVEFIT, which is based upon Numerical
Recipes.
.
MPFIT has additional capabilities not found in CURVEFIT. Model parameters can
be "frozen" (that is, held constant during the fitting process). Simple
boundary constraints can be imposed on parameter values, which can be helpful
to keep parameters from becoming negative, for example. Please see the
documentation for the PARINFO keyword if you wish to use this facility.
The software is written for the commercial language "IDL", but works in
large parts with GDL as well. Since I don't have much experience with
GDL/IDL, any input, help, co-maintenance or even taking over the packaging
is appreciated.
The software will be maintained within te Debian Astronomy Team.
A git repository will be created on alioth at
https://anonscm.debian.org/cgit/debian-astro/packages/mpfit.git
The package will *require* gnudatalanguage. Feel free to start a discussion
if this is a good idea and or if and how the commercial package (IDL)
should be supported.
Best regards
Ole
