THE OUTPUT WINDOW
This window is automatically opened when the P5 program calls the Maple/Reduce part of P5, i.e. each time one tries to evaluate a vector field (or when one tries to plot a greatest common factor in the plot window).
One should not use this window to extract mathematical information on the vector field; use this window rather to find out if something has gone wrong, to see how long the computation has been going on, to terminate a computation that is too lengthy, etc. (To see extensive math information, use the
in the main
P5 window after the computation has finished.)
For example, to see if a computation is finished, the window could look like
The sentence "We have finished the study of the vector field" indicates a successful study.
Sometimes, the program fails for a reason that is not immediately clear. One could get a window like:
In this particular case, something went wrong with the program settings: P5 failed to start maple. Use the
Settings Window to enter the settings.
Also the following error is an indication that something is wrong with the P5 settings:
In this particular case, the P5 base path is chosen wrong.
Sometimes, you have mis-entered the vector field:
You get this error when the vector field you have specified is not polynomial, when the coefficients remain unknown (most likely you have a typo-error in the names of the parameters or you have x2 somewhere instead of x^2...).
In the last example, you can see how Maple reacts when it has a quite lengthy computation:
In this particular example, Maple is busy trying to solve for all singular points for a system of degree 20.

Note: closing the output window using the
button will not terminate any
ongoing maple session.
