inverse2 Phi
inverse2(Phi,Verify=>true)
inverse2(Phi,Verify=>false)
This assumes that the graph of the input map Phi is defined by a simplified system of equations, which may not be true. If the option Verify is set to true, which is the default choice, then it is verified that the left and right composition of Phi with the returned map is the identity, throwing an error if this is not the case.







The object inverse2 is a method function.
