it is matlab code and is for systems and signals by porakis that is very good for all

empirical mode decomposition

各种随机数产生程序，包含了随机数产生的各种方法。(All kinds of random number generator program includes various methods of random number generator.)

matlab中结合小波和偏度对故障信号的处理(matlab combination of wavelet and skewness of the fault signal processing)

该程序可实现图像四方向频谱划分，通过该程序，衣服图像四方向的信息会很好的展现出来。(This program can be divided into the spectrum of image four directions, through the program, four-direction image information clothes would show up well.)

说明：  分段线性样条差值的matlab仿真，用于数值计算(Piecewise linear spline margin matlab simulation, for the numerical calculation)

matlab代码，是在windows环境下，利用matlab r2010a开发的一段关于回归分析的代码(matlab code is in the windows environment, using matlab r2010a developed a regression analysis on the code)

HHT的基本理论(黄先生的原文) 小波板换希尔伯特黄变换；理算小波变换原文(Signal filtering, Wavelet transform, Hilbert-Huang transform DWT (Discrete Wavelet Transform) och HHT(Hilbert-Huang Transform).)

说明：  matlab实现惯导数据的初步解算，能够得到位置、角度等的误差分析(Matlab realizes the initial solution of inertial navigation data)

该matlab函数计算自由空间里有限厚度、无限大的各向同性媒质块（允许频率色散）在任意极化、任意入射角度的来波下的反射和透射系数，用户可以指定计算的频段。(Matlab function freely in the space of finite thickness, an infinite isotropic medium block (frequency dispersion permit) at any polarization, arbitrary angle to the wave of reflection and transmission coefficients, the user can specify the calculation of the band.)
