DependentVariables

DependentVariables
is an option for NDSolve and other functions that specifies the list of all objects that should be considered as dependent variables in equations that have been supplied.

Details Details

With DependentVariables->Automatic, the dependent variables are determined from the equations.
DependentVariables->{u₁, u₂, ...} specifies a complete list of dependent variables representing functions that should be solved for, even if the solutions are not eventually returned.
DependentVariables->{uspec₁, uspec₂, ...} can be used to specify ranges for dependent variables.
Possible forms for are:

	u	u has range Reals or Complexes
	Element[u,Reals]	u has range Reals
	Element[u,Complexes]	u has range Complexes
	Element[u,{v₁,...}]	u has discrete range
	{u,u_min,u_max}	u has range
	uspec_i⧴action_i	perform when is no longer satisfied
