- -random
- A good choice for use with xscreensaver: picks random parameters from a built-in list.

- -C
*n* - Specifies the minimum color index to be used for negative exponents

- -D
*n* - Specifies the "dwell" or number of iterations over which to average in order to calculate the Lyapunov exponent. Default is 50.

- -H
*n* - Specifies the height of the window. Default is 256.

- -L
- Indicates use log(x) + log(y) rather than log(xy).

- -M
*r* - Specifies the real value to compare exponent values to for indexing into a color wheel. The default value is 1.0.

- -O
*n* - Specifies the minimum color index to be used for positive exponents

- -R
*p* - Specifies pseudo-random forcing with probability
*p*of using parameter value 'a'.

- -S
*n* - Specifies the "settle" or number of iterations prior to the beginning of the calculation of the Lyapunov exponent. Default is 50.

- -a
*r* - Specifies the real value to use as the minimum parameter value of the horizontal axis. Default is 2.0 for the logistic map.

- -b
*n* - Specifies the real value to use as the minimum parameter value of the vertical axis. Default is 2.0 for the logistic map.

- -c
*n* - Selects one of six different color wheels to use. The default color wheel is a rainbow palette.

- -F
*10101010* - Specifies the "Function" forcing function to use. The example above would alternate between iterating the circle and logistic maps. An argument of "-F 2323" would alternate between left and right logistic maps. The default is to only use the single specified map (see the description of -m).

- -f
*abbabaab* - Specifies the forcing function to use. The default is to alternate between the "a" parameter and the "b" parameter.

- -h
*r* - Specifies the real value to be used as the range over which the vertical parameter values vary. The default is 1.0.

- -i
*r* - Specifies the real value of the initial condition to use. Default is 0.65.

- -m
*n* - Selects between available non-linear maps of the unit interval. A value of 0 specifies the logistic map. A value of 1, the circle map. A value of 2, the left-logistic. A value of 3, the right-logistic. A value of 4, the double-logistic. The default is 0, the logistic map.

- -o
*filename* - Specifies the output filename to be used. If the -o option is given, this file will automatically be written out at the completion of the drawing. If it is not specified, a default filename of lyap.out is used and only written if the 'f' or 'F' keys are pressed during a run. The format of the output file is PPM for color and PGM for monochrome. The parameters used to calculate the picture are included as comments at the beginning of the output file.

- -p
- Switches color indices for negative and positive exponents. Generally, causes negative exponents to be displayed in more detail while darkening and narrowing the color range for positive exponents. This can be toggled during runtime by pressing the 'p' key.

- -r
*n* - Specifies the maximum rgb value to be used. Default is 65000.

- -s
*n* - Specifies the length of the color wheel spin.

- -v
- Prints out the various values to be used and exits.

- -w
*r* - Specifies the real value to be used as the range over which
the horizontal parameter values vary. The default is 1.0.
