Computer codes which were used to compute the illustrative results
from this paper can be downloaded below. Computations from Sections
2, 3 and (partially) 5 were done in Matlab. A Matlab file "FigureX.m"
plots the corresponding Figure X in the paper.
Computations from Section 4 and Figure 5.4 were done in Fortran 90.
A Fortran 90 code "FortranFigureX.f90" stores the computed data in
the corresponding data file "FigureX.dat" which is plotted (visualized)
in Matlab using the Matlab file "FigureX.m". All codes were successfully
tested on both, Unix and MS Windows, versions of Matlab. Comments and
suggestions can be sent to my e-mail.
