DependentVariables

DependentVariables
is an option which specifies the list of all objects that should be considered as dependent variables in equations that have been supplied.
  • DependentVariables->{u1, u2, ...} specifies a complete list of dependent variables ui representing functions that should be solved for, even if the solutions are not eventually returned.
EXAMPLESCLOSE ALL
Basic Examples   (1)
Save only the solution for x[t]:
Plot the solution x[t] as a function of t:
Save only the solution for x[t]:

Out[1]=
Plot the solution x[t] as a function of t:
In[2]:=
Click for copyable input
Out[2]=
Applications   (1)
Set up a very large system of equations:
Solve for all of the dependent variables, but save only the solution for x1.
This saves a lot of memory versus saving all the solutions:
