摘要：
In order to solve nonlinear least squares problems, a new method which is based on the Structured Secant method by Huschens combining with a special quasi-Newton equation is presented. The performance of the new method is analyzed in terms of the number of iterations and the feasible region of the initial point in comparison with the special quasi-Newton methods proposed by Z.Wei et al. using two test functions with several initial point. Numerical results show that the method is efficient.
