Ikeda time series

ikeda -l# [-A# -B# -C# -R# -I# -o outfile -x# -V# -h]

-l number of points x,y (l=0: infinite)
-A parameter a (0.4)
-B parameter b (6.0)
-C parameter c (0.9)
-R initial Re(z)
-I initial Im(z)
-x number of transients discarded (10000)
-o output file name, just -o means ikeda.dat
-V verbosity level (0 = only fatal errors)
-h show this message

Creates iterates of the Ikeda map (K. Ikeda, Opt. Commun., 30, 257, (1979)) (Re(z) and Im(z)).
