GnuPlot : language c

* You need a C compiler to compile the code (source).
* For this work, I use Dev-C++ 4, and DJGPP two freewares.
* You can also use Ch 4.0 released (C99). The Standard Edition is free in all platforms.
* The graphic interface is gnuplot.
* You can download this freeware here : Gnuplot Central.
* My work is also a Freeware.
* Windows, Linux.

In these packages, you can verify the result into GnuPlot.
