| Abstract: | This paper introduces a method of using MATLAB for solving large-scale problems ,based on the feature of the large computing and saving brought by methods of gradient and imitational Newton in engineering and scientitle computing. In this paper, we have presented some mathematical models and relevant functions for solving the large-scale problems and analysed their fesibility. In the last part, we illustrate, by an example of solving nonlinear equtation of Jaccobi matrix, the method of using MATLAB for solving problems in detail. |
