I agree with everything Martin said, *except* that it's named MPFIT,
and it's located here :-)


There are some specialized peak-fitting procedures ready to use there.

Also, if you still insist on using splines, then I suggest you use the
SPL_INIT and SPL_INTERP (sp?) functions.  They seem to be much faster
and more robust.

Good luck,
