An interactor algorithm for invertibility in general nonlinear systems

Over the field of meromorphic functions, the interactor algorithm for affine nonlinear systems is extended to general nonlinear systems in this paper. Compared with the Singh algorithm for general nonlinear systems, it is not necessary to permute the components of the output at any step of the interactor algorithm procedure. Therefore, the procedure can be carried out in a unique way, which means that the algorithm procedure is simplified and the operation result is unique. An example is used to demonstrate the procedure of the interactor algorithm and the results show its validity.
