  • 逆broyden迭代法
    说明:  逆BROYDEN迭代法求解非线性方程组:是一种相对比较新的一种方法,克服了牛顿迭代法需要求导数和求逆的缺点。本程序提供解法和画图流程,注意多迭代几步(Inverse BROYDEN iteration method is a relatively new method for solving nonlinear equations, which overcomes the shortcomings of Newton iteration method in derivative and inversion. This program provides solution and drawing process. Remember more several steps of iteration.)
