THE (MAIN) P5 WINDOW

This window is usually the first one to visit. By pressing
the main window unfolds in a larger window:

Here you load or introduce the Polynomial Differential System you will study, adjust the parameters for
the study, and execute the main part of the computations.
The first thing to do is to enter a name of the vector field file you want to open (or a name for a new file that you want to create). You type in the name in the
field. Spaces in the filename are allowed. Default extension is .inp, but it is not necessary to manually add this extension. You can also use the
button to browse all directories for input files. Note that the file contents is not automatically loaded after you enter the name; you have to press the
yourself.
-
The Option Set
will allow you to choose between two different computer
algebra systems. For P5, only Maple is supported.
-
The Option Set
will toggle you between two options.
The default option is Run File. It will make the program to be executed
completely making the study of the Polynomial Differential System and preparing
everything to integrate every separatrix of it. Sometimes you may wish to select
option Prepare File. This option generates a MAPLE file (.txt).
Now you can run the file directely with MAPLE. You may be interested in this option
if the amount of computations is very large and you prefer to run a MAPLE
program in batch mode instead of running it in graphics-user-interface-mode.
-
The Option Set

will allow you to choose among a complete study of
all singular points, restrict yourself to the finite or infinite ones, or make the study of only one
finite singular point. In the later case you should introduce the point
by entering its coordinates in
and
.
-
The Option Set
will toggle you between two options. The default option
is No and reduces the amount of information that you get when you press the button
in the
P5 window to the most interesting
features of the Polynomial Differential System you are going to study. The option yes
will fill that file with an exhaustive description of every step followed by the program.
-
The button
will show/hide the
parameter-subwindow:

Once you have entered all the data one could choose to make the P5-window smaller (just in order to
save some space on the screen).
-
The button
will show/hide the
vector field-subwindow:

Once you have entered all the data one could choose to make the P5-window smaller (just in order to
save some space on the screen).
-
The button
will load the already existing file which name has been
provided in the
P5 window. You will get an error message if the file
does not exist.
-
The button
will save all the changes you have done to the Polynomial
Differential System and the running parameters into the file which name has been provided in
the P5 window.
-
The button
will start the execution of the study of the Polynomial
Differential System. You must wait until the terminal window from which you are executing the
program shows a message saying that the study is ended:

-
The button
will close all P5 windows and stop stop the
program.
