GetEquations[dae]
returns the list of equations stored in dae
Command structure of GetEquations.
Given a DAEObject dae, GetEquations returns the equation system stored in the object as a list of
equations. In case of an AC DAEObject the internal matrix representation is converted to a list of
linear equations.
