System object: dsp.DCT
Create discrete cosine transform object with same property values
C = clone(H)
C = clone(H) creates
an instance of the current discrete cosine transform object,
with the same property values as
H. If an object
is locked, the
clone method creates a copy that is
also locked and has states initialized to the same values as the original.
If an object is not locked, the
clone method creates
a new unlocked object with uninitialized states.
