摘要：
We present a variant of the directional Newton method for solving a single nonlinear equation in several variables. Under suitable assumptions, we prove the cubic convergence speed of this new method. This method is suitable for parallel implements. The related parallel algorithms are discussed. Numerical examples show that the new method is feasible and efficient, and has better numerical behavior than the directional Newton method.
