Python实现Jacobi迭代法 接下来,我们通过Python来实现Jacobi迭代法,具体代码如下: AI检测代码解析 importnumpyasnpdefjacobi(A,b,x0=None,tol=1e-10,max_iterations=100):# 确保A是一个方阵n=A.shape[0]ifx0isNone:x0=np.zeros(n)x=np.copy(x0)forkinrange(max_iterations):x_new=np.zeros_like(x)f...
使用mermaid类图表示我们的操作对象及其关系: -attribute tolerance: float+method jacobi_iteration(A: Array, b: Array, x_init: Array) 结论 在这篇文章中,我们介绍了如何在Python中实现Jacobi迭代法的迭代矩阵。通过步骤清晰的结构,我们能够轻松理解这一过程。不论是通过定义系数矩阵和常数向量、计算迭代矩阵还是实...
以下是使用Python实现Jacobi迭代法的代码: ``` import numpy as np def jacobi(A, b, x0, tol=1e-6, max_iter=1000): """ Jacobi iteration method to solve Ax=b. :param A: coefficient matrix :param b: constant vector :param x0: initial guess of solution :param tol: tolerance of error...

The performance of the system under the use of the suggested method is compared with that of a Linear Quadratic Regulator (LQR). For that purpose, class namedPyDiffGameLQRComparisonis defined. A comparison of a system should subclass this class. As an example, for the masses and springs syst...
