Higher-Order-Spectral-

离散信号的时域分析，输出各种离散信号的波形图，有利于各初学者理解揣摩(Time domain analysis of discrete signals, the output waveform of various discrete signals, try to figure out is conducive to the beginner to understand)

这是用于计算转子——轴承系统不平衡响应的程序，转子用集总参数法简化，轴承支撑为各项同性支撑(This is used to calculate the rotor- bearing system unbalance response procedure, the rotor with a simplified lumped parameter method, the bearing support for the homosexual support)

This is an implementation of Particle Swarm Optimization algorithm using the same syntax as the Genetic Algorithm Toolbox, with some additional options specific to PSO. Allows code-reusability when trying different population-based optimization algorithms. Certain GA-specific parameters such as cross-over and mutation functions will not be applicable to the PSO algorithm. Demo function included, with a small library of test functions. Requires Optimization Toolbox.

能够进行各向异性的差分等效介质（Differential Effective Medium Model）理论，获得各向异性介质的弹性张量(This programme could be used to build anisotropic elastic model by anisotropic Differential Effective Medium Model)

牛顿插值法，可用于非线性拟合，并返回在某点出的近似函数值。(Newton interpolation method can be used for nonlinear fitting, and the function returns the approximate value at some point out.)

瑞利信道仿真程序，请大家参考。 瑞利信道仿真程序，请大家参考。(Rayleigh channel simulation procedures, please refer to everyone.)

小扰动偏导求解,利用matlab的符号运算(small pertub)

数值积分法通过matlab实现，对于初学者非常有用。从书上下载的源代码。(Achieved by numerical integration matlab, very useful for beginners. Downloaded from the book source code.)

说明：  SVM 的代码,工具箱的使用内部有详细的说明,请读者看看Matlab代码中参数使用,将训练数据以矩阵形式输入,即可使用(SVM code, the use of the toolbox there are detailed instructions, please take a look at Matlab code readers parameter use, will be a matrix of training data input, you can use)

主程序为随机共振，包含四阶龙格库塔和信噪比子程序(main is stochstic resonance,including runge-kutta and SNR.)
