Hi,

In order to test a (precise and very fast) library of transcendental
functions, together with a graphical interface for real-time analysis,
selected functions are being made available to the public for critique.
Currently you may enjoy the marvels of the:

Gamma Function - Gamma(x)

The computer program runs in MS DOS or Windows on standard x86 machines
with an FPU and SVGA (VESA standard). Detailed specifications and GUI
description are available at: www.iging.com/Transcendental.

Your constructive feedback is very much appreciated.

Um.

I must ask why you post this everywhere but sci.math.

Also, I must ask why you think people would use your sourceless
executable in anything.

I did; it had not been retrieved by your server yet, I guess. I posted with
Google
and they do not allow crossposting to more than 4 groups at a time. Hence,
I
have split my posting to sci.math.* (4 groups) and sci.physics.* (4 groups).

The freely available computer program contributes to the better
understanding of the Gamma function in the entire real domain.
Furthermore, the reciprocal gamma function (1/Gamma(x)) is
also available on the site above.

I don't know from where you take the idea that I should work for
you for nothing. Giving away the source code is giving away your
intellectual rights (on your creative work). Sorry.

What is there to understand? How is this different from using
gnuplot?

Furthermore, the reciprocal gamma function (1/Gamma(x)) is
also available on the site above.

immoland-~ gnuplot
[snip]
gnuplot plot [0:10] gamma(x)
gnuplot plot [0:10] 1.0/gamma(x)

There's really not much to see out past x=10... it just keeps getting
bigger (or smaller) pretty fast.

I don't know from where you take the idea that I should work for
you for nothing.

Well, you did give the executable away for free. And the only reason to
use a new implementation of the gamma function would be if it were
faster than those availible already. So you'd want the source (or some
sort of library file). A program that simply plots gamma(x) seems redundant.

Giving away the source code is giving away your
intellectual rights (on your creative work). Sorry.

That's not true really. You could certainly distribute the source under
a "do not share this" license.

It doesn't really matter though, since plotting gamma(x) is pretty easy
with exisiting (free) tools.

Only few use Linux (or am I wrong?).

: gnuplot plot [0:10] gamma(x)

What about the really interesting part, say the interval [-10,0] ?

From your response, it looks as if you had not used my program. If
you did, you would have noticed that the function(s) calculates extremely
fast and precise. Applications on x86/7 hardware that need a small, precise
and very fast library of transcendental functions will not find it in
gnuplot.

as Matthew Nobes indicated, a stand alone evaluate and plot of the
Gamma function is not useful or interesting enough to pay for and
its not useful useful or interesting to take the risk of downloading
an executable that may contain a virus or do something bad to my computer.

Useful source code for Gamma and other functions may be found at
www.nr.com (home page of numerical recipes).

Utterly wrong. What makes you think people would want to download and
run a binary executable that they found on Usenet? Your program might as
well contain the cure for cancer but I don't care - nobody in their
right mind is going to use it since it's a ridiculous security risk.

Anyway, if you're so pleased with it, why not release the source and let
people judge for themselves?

The stand alone Gamma, Reciprocal Gamma and Bessel function of the
first kind are free. Anyway, thank you for the critique.

You don't feel it sort of goes hand in hand with your request for others
to test your code for you for nothing?
