    The function accepts either 1 or 4 parameters:

    ``ss2tf(sys)``
        Convert a linear systemintospacesystem form. Always creates a
        new system, even if sys is already a StateSpace object.
        Convert a linear systemfrom statespaceinto transfer function form. Always creates a
        new system.

    ``ss2tf(A, B, C, D)``
        Create astate space system from the matrices of its state and
        Create atransfer function system from the matrices of its state and
        output equations.
