Notes on Running HomCont Demos.

HomCont demos are given in the following chapters. To copy all files of a demo xxx (for example, san), move to a clean directory and type demo('xxx'). Simply typing make or make all will then automatically execute all runs of the demo. At each step, the user is encouraged to plot the data saved by using the command plot (e.g., plot('1') plots the data saved in b.1 and s.1).

Of course, in a real application, the runs will not have been prepared in advance, and AUTO-commands must be used. Such commands can be found in a table at the end of each chapter. A sequence of detailed AUTO -commands will be given in these tables as illustrated in Table 20.1 and Table 20.2 for two representative runs of HomCont demo san.

The user is encouraged to copy the format of one of these demos when constructing new examples.

The output of the HomCont demos reproduced in the following chapters is somewhat machine dependent, as already noted in Section 12.4. In exceptional circumstances, AUTO may reach its maximum number of steps NMX before a certain output point, or the label of an output point may change. In such case the user may have to make appropriate changes in the AUTO constants-files.

Table 20.1: These two sets of AUTO-Commands are equivalent.

COMMAND	ACTION
ld('san')	load the problem defition
run(c='san.1',h='san.1')	get the HomCont constants-file and run AUTO /HomCont
sv('6')	save output-files as b.6, s.6, d.6
@H san 1
@sv 6

Table 20.2: These two sets of AUTO-Commands are equivalent.

COMMAND	ACTION
run(c='san.9',h='san.9',s='6')	get the HomCont constants-file and run AUTO /HomCont; restart solution read from s.6
ap('6')	append output-files to b.6, s.6, d.6
@H san 9 6
@ap 6
