Tetration $f={\rm tet}_b(x)$ in the $x$,$b$ plane shown with levels $f\!=\!\rm const$ for $-2 \! < \! x \! \le \! 2$ , $1 \! < \! b \! \le \! 5$.

The following files are used for generation of this image:
tetre2215.cc, main program that does the plot
ado.cin, routine that writes the head of the eps file
conto.cin, routine that draws the levels of a function of 2 variables
tetreal2215.tex (adding of marks of axes and levels)

In addition, you need C++ compiler, Latex and convert software installed at your computer in order to generate the pic.
Assume the files mentioned are saved to some folder ~/PicsFromTori/
Then the image can be generated with sequence of commands below:

~/PicsFromTori>make tetre2215
~/PicsFromTori>./tetre2215
~/PicsFromTori>pdflatex ./tetreal2215
~/PicsFromTori>convert tetreal2215.pdf tetreal2215.gif

The last command is necessary if you have improved something and want to upload the result to TORI (or to another mediawiki site): unfortunately, the mediawiki yet support neither eps nor pdf format.
