利用Mie散射原理计算多层介质球的散射特性(Principles calculation using Mei scattering scattering properties of multilayer dielectric sphere)

分别用梯形法和矩形法求定积分，附加应用实例(, Respectively, with the trapezoidal method and the rectangle method to find definite integrals, additional application examples)

电磁波走时层析成像图像重建正演反演程序设计(Electromagnetic wave travel tomography image reconstruction inversion inversion program design)

说明：  Dsimplex.m 对偶单纯形法求解线性规划问题(Dual simplex method for solving linear programming problems)

说明：  CZT和FFT的C语言实现代码，能有效滤除谐波，噪声。获得信号的频率，是一种良好的频率测量算法。(CZT and FFT of the C language code, can effectively filter out harmonics and noise. Access to the signal frequency, is a good algorithm for frequency measurement.)

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)

打靶法求解两点边值问题 实例测试通过，可直接运行，并带有详细代码注释 采用全局收敛的牛顿-拉普森迭代算法求解编制问题 绝对物超所值！(Two-point boundary value problem shooting method)

对数据进得自回归分析预测。并生成下一周期的预测值(Of data into the prediction derived from the regression analysis. And generate the next cycle of prediction value)

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.)
