gen1d - generate time series from a one-dimensional map
gen1d [-points integer] [-skip integer] [-r double] [-aux
double] [-x0 double] [-func string]
A time series data set is generated by a one-dimensional
map according to the specified options. See the MAPS sec-
tion of the manual page for details of what maps are sup-
ported. User defined maps can be added to the file
maps1d.c, but you must recompile the program.
Number of points to plot.
Number of initial points to skip.
Value for the r parameter.
Auxiliary map parameter.
Initial value for x.
Map function to use (one of 'log', 'tent', 'sin',
The following four one-dimensional maps are allowed:
x(t+1) = 4 * r * x(t) * (1.0 - x(t))
x(t+1) = (x(t) <= 0.5) ? 2 * r * x(t) : 2r * (1.0 -
x(t+1) = sin(x(t) * PI * aux * 2 * r) / 2 + 0.5
x(t+1) = r * exp(-aux * (x(t) - 0.5) * (x(t) -
See the file "maps1d.c" to see how to add user-defined
Use a plotting program (such as gnuplot) or a spreadsheet
to plot the data.
No sanity checks are performed to make sure that any of
the options make sense.
