Basic PLAUT-Commands.

The principal PLAUT-commands are

bd0

 : This command is useful for an initial overview of the bifurcation diagram as stored in fort.7. If you have not previously selected one of the default options d0, d1, d2, d3, or d4 described below then you will be asked whether you want solution labels, grid lines, titles, or labeled axes.

bd

 : This command is the same as the bd0 command, except that you will be asked to enter the minimum and the maximum of the horizontal and vertical axes. This is useful for blowing up portions of a previously displayed bifurcation diagram.

ax

 : With the ax command you can select any pair of columns of real numbers from fort.7 as horizontal and vertical axis in the bifurcation diagram. (The default is columns 1 and 2). To determine what these columns represent, one can look at the screen ouput of the corresponding AUTO run, or one can inspect the column headings in fort.7.

2d

 : Upon entering the 2d command, the labels of all solutions stored in fort.8 will be listed and you can select one or more of these for display. The number of solution components is also listed and you will be prompted to select two of these as horizontal and vertical axis in the display. Note that the first component is typically the independent time or space variable scaled to the interval [0,1].

sav

 : To save the displayed plot in a file. You will be asked to enter a file name. Each plot must be stored in a separate new file. The plot is stored in compact PLOT10 format, which can be converted to PostScript format with the AUTO-commands @ps; see Section 7.4.

cl

 : To clear the graphics window.

lab

 : To list the labels of all solutions stored in fort.8. Note that PLAUT requires all labels to be distinct. In case of multiple labels you can use the AUTO command @lb to relabel solutions in fort.7 and fort.8.

end

 : To end execution of PLAUT.
