Equation Trekker Package Symbol

InitializeGenerator

InitializeGenerator[gen, problem, dvars, {t, t_min, t_max}, opts]
returns the trek generator gen[data] when called by EquationTrekker. The specific form of data depends on the trek generator gen.

IntializeGenerator[gen, problem, dvars, opts]
returns a trek generator which does not use an independent variable.

MORE INFORMATION

To use InitializeGenerator, you first need to load the Equation Trekker Package using Needs["EquationTrekker`"].

EquationTrekker[problem, dvars, {t, t_min, t_max}, TrekGenerator->{gen, subopts}] calls InitializeGenerator[gen, problem, dvars, {t, t_min, t_max}, {subopts}] to initialize the generator gen.

EquationTrekker[problem, dvars, None, TrekGenerator->{gen, subopts}] should be used when gen does not use an independent variable, in which case EquationTrekker will call InitializeGenerator[gen, problem, dvars, {subopts}].

A new generator newgen can be created by giving the additional InitializeGenerator definition, newgen/:IntializeGenerator[newgen, ...]:=newgen[data]. In addition, definitions for the following DownValues of the function newgen[data] need to be given:

	newgen[data]["Variables"[]]	list of variables
	newgen[data]["Display"[]]	problem description to be displayed
	newgen[data]["DisplayMode"[]]	the display mode, either "Line" or "Points"
	newgen[data]["FormatTrek"[t₀,dvars₀,{t_min,t_max}]]	information used to tag TrekData
	newgen[data]["ChangeParameters"[prules]]	generator with data modified by new parameters
	newgen[data]["GenerateTrek"[dvars₀,{t₀,t_min,t_max}]]	list of data points to plot, with initial point given by dvars₀ and t₀
