Hello everybody!
My name is Alex Navarro. I am a material researcher from Polytechnic
University of Valencia (Spain).
I have been using OpenOffice.org (OOo) and other free software products
for some four years. I prefer these programs instead of another
'proprietary' ones. But I still miss a feature in OOo which forces me to
use 'the other' products.
In my daily work I need to fit some complex formulae to experimental
data. This process involves numeric calculus and different fitting
routines, by common least-square minimization algorithms. I would like
to build these routines, but this task would take me some years, since I
am used to program with math-oriented languages, and very little Java,
but no other programming language. What is more, Objects and Classes are
still strange for me.
This is the main reason that keeps me using proprietary spreadsheets.
They are not the best way to perform these calculi, but they usually
work, and are user-friendly. If someone can give me ideas to speed up
this work, or simply program these routines, that would be very nice.
Thank you for all.
Alex
Your requirements are pretty specialized, and I doubt if there is much
demand for their implementation in a general office suite. There is a
commercial program designed for engineering calculations. It's called
Mathcad. Here is the website:

I have used this program in the past, and I really like it. Unfortunately,
I have not found a free substitute for it. Maybe someone else has found a
free substitute. It only runs on Windows, but a Spanish language version
is listed on the website.
