下面我们列举一个Nonlinear algebraic equation [secant method])的例子:使用the secant method找到以下非线性方程的根,使用 1×10^{-5} 的收敛误差和初始估计 u^{0} =2.0。检查收敛速率。 解:由于问题只有一个变量,因此该问题成为一个非线性代数方程;P(u)相对于u的导数变为 下面是求解非线性方程
Thus, the root of f(x) = cos(x) + 2 sin(x) +x2as obtained from secant method as well as its MATLAB program is -0.6595. Check: f(-0.6585) = cos(-0.6585) + 2 sin(-0.6585) + (-0.6585)2= 0.0002 (OK). If you have questions regarding secant method or its MATLAB code, bring...

The one step secant (OSS) method is an attempt to bridge the gap between the conjugate gradient algorithms and the quasi-Newton (secant) algorithms. This algorithm does not store the complete Hessian matrix; it assumes that at each iteration, the previous Hessian was the identity matrix. This...
