""" **Description**

        State derivative interface.

    **Example**

        ::

            from diamondback import IQ
            import numpy

            class Test( IQ ) :

                def __init__( self ) -> None :

                    super( ).__init__( )

                    self.q = numpy.array( [ 0.0, 0.1 ] )

            test = Test( )

            test.q[ : ] = 0.1
