For polynomial fitting see:

LAPACK is part of Intel MKL, shipped with Intel Fortran Professional 11.0 onwards.

Hi.  I am still trying to solve my fitting problem.  Although I have found plenty of very well educated advice at this forum my problem is still unsolved and it seems to get every time more complicated.  Anyways.  I was considering what you said.  And although I do not have MKL nor IVF I have access to LAPACK through netlib.org.  I have been looking more in the LAPACK routines offered there but for me is an ocean of confussion with so many options and so much stuff I do not understand.  But I was wondering if specifically you know which routine in LAPACK would be useful for me to use to fit a forth order polynomial (or an exponential) to experimental data X and Y. Would you be kind to guide me to a routine I could use for this purpose?  I would really appreciate it.  Many thanks.
