中文说明：拟牛顿法是求解优化问题的一种重要方法，本文在 Matlab 平台上，运用 拟牛顿法对最小值问题进行了无约束优化求解。计算结果表明，拟牛顿法能够比 较精确地计算函数的极小值。
English Description：
Quasi-Newton method is an important method for solving optimization problems, based on the Matlab platform, using quasi-Newton method for unconstrained optimization least value. Results showed that the quasi-Newton method can more accurately calculate the minimum value of the function.
