很好用的有关矩阵的各种操作，包括求逆，特征值，特征向量，svd分解等(good part of the matrix of various operations including inverse, eigenvalues, eigenvectors, svd decomposition, etc.)

Matlab 算法寻找Bessel函数的零点。(find the zero point of Bessel functions)

信息是个很抽象的概念，本文介绍了熵的概念，并介绍计算方法(information is a very abstract concept, this paper introduces the concept of entropy, and the calculation method introduced)

实现高斯厄米特积分，可以直接更换f函数，得到所求的积分(High the Sie Mitt integral to replace the f function, ask the integral )

说明：  最速下降法就是梯度下降法,可以用于求解最小二乘问题(线性和非线性都可以)。可以说是求解机器算法的最古老、最经典的模型，另一种常用的方法是最小二乘法。(The steepest descent method is the gradient descent method, which can be used to solve the least squares problem (both linear and non-linear). It can be said that it is the oldest and most classical model for solving machine algorithm. Another commonly used method is the least square method.)
