Direction Fields and Solution Curves ( DEplot )
Replace the question marks ( ? ) in the following input regions to create the direction field for your model.
> VAR := { ? }; # specify the variables in the model
> DOMAIN := ? = ? .. ? ; # specify a reasonable interval for the independent variable
> RANGE := ? = ? .. ? ; # specify a reasonable interval for the dependent variable
> plotSLOPE := DEplot( MODEL, VAR, DOMAIN, RANGE, arrows = MEDIUM ):
> plotSLOPE;
>
Next plot one or more solution curves corresponding to the specified initial conditions.
> DEplot( MODEL, VAR, DOMAIN, [ [IC] ], linecolor = BLUE, arrows = MEDIUM );
> DEplot( MODEL, VAR, DOMAIN, [ [IC1], [IC2], [IC3] ], linecolor = [BLUE, GREEN, BLACK], arrows = MEDIUM );
>
Look at the help under plot,options to see other ways you can customize your plots.
