i am looking for c or c++ source code for an implementation of
iterative reweighted least squares algorithm. Is there any simple code
available which implements IRLS? Thank you in advance.

I have an implementation that is quite close to this although it
originated from the maximum likelihood method. You can have a look at
the method at

Statistical model of systematic errors: linear error model
http://dx.doi.org/10.1016/0169-7439(96)00004-4

or preprint

http://evgenii.rudnyi.ru/doc/papers1/96cils_syserr.pdf

The code is available from my site at

http://evgenii.rudnyi.ru/doc/misc/tdlib.html

The previous version of the code is at (it is smaller and probably
simpler)
