I would greatly appreciate some help at finding some good documantation on SciLab especially the data fitting features. Most of web sites I've been suggested as containing plenty of worked out examples cannot be found by any browser.
I'm not necessarily hooked on SciLab. Any similar tool that provides a broad suite of different fitting methods (not just the Least Squared ...) will make me happy. Thank you in advance. MEM
Hi Maura,
Depending on what you're trying to fit, and on what principles,
you might be well served by R:
http://www.r-project.org
which offers just about any of the model-fitting methods you
might possibly need from the world of statistical data analysis.
On the other hand, if you want to make a "deterministic" fit
(essentially interpolation) to numerical data which are not
subject to "statistical scatter" in their determination, then
this might not help too much. This is more in the "Numerical
Analysis" area, where (as well as SciLab which I've not used
since it early versions several years ago) there are very
powerful packages such as octave (OS MatLab surrogate). You
can also do this sort of thing in R (since it allows you to
program pretty much any numerical routine you want), but you'd
probably be better off with software where this sort of thing
has already been built in on a well-designed and well-tested
basis; OK if you know what you're doing, though.

Hope this helps!
Ted.
