3.6.9 GetParameters
GetParameters[dae]
returns the list of parameters stored in dae
Command structure of GetParameters.
Given a DAEObject dae, GetParameters returns the list of parameters occuring in the equation
system of the object.
Note that GetParameters differs from GetDesignPoint in that it returns only those parameters
which appear in the equations of dae. Moreover, it returns a list of symbols, not a list of replacement
rules.
