Matrix Identity

In Blender I can do the following to check if an object has been transformed:
ident_matrix = Matrix.Identity(4) obj_moved = obj.matrix_world != ident_matrix
I don't see any matrix identity functions in C4D.
Am I missing something?If there isn't, what is the best way to check if an object has been transformed?
Thanks,
Chris

Couldn't find anything, so I guess you have to roll your own:
def CheckIdentity(op) : matrix = op.GetMg() if matrix.off == c4d.Vector(0,0,0) and \n matrix.v1 == c4d.Vector(1,0,0) and \n matrix.v2 == c4d.Vector(0,1,0) and \n matrix.v3 == c4d.Vector(0,0,1) : return True else: return False
This does the trick.

This does what I wanted, and is the simplest answer:
obj.GetMg() == Matrix()
The function above could be used to check for a particular transformation, but it is overkill for this.
