FFT和Hilbert变换工具包，但是和MATLAB相比要慢些(FFT and Hilbert transform tool kits, and MATLAB slower than some)

三维光子晶体布拉格衍射峰寻峰代码，可以得到布拉格衍射峰峰位、半峰宽、峰强的详细信息(Three-dimensional photonic crystal Bragg diffraction peak peak search code Bragg diffraction peak positions, FWHM, peak intensity Details)

本帖调用自编函数（grating）绘制光栅条纹图像，通过例子讲解水平、竖直、环状和辐射状光栅条纹图像的绘制，用黑白和彩色显示效果给大家视觉上的震撼。调用自编函数时，可以通过成对出现的参数控制条纹的方向、颜色、周期、相位角等。(This post calls self-function (grating) draw grating image, by way of example to explain the horizontal, vertical, circular and radial grating image rendering, with monochrome and color display give you visual shock. Self function call, the parameters can be controlled by pairs stripe orientation, color, period, phase angle.)

说明：  经典谱估计的所有算法，有注解，全面。直接法，间接法，BATLETT法，WELCH法等。(All the classic spectral estimation algorithm, annotated and comprehensive. Direct method, indirect method, BATLETT law, WELCH law.)

镜像经验模态分解，可以实现信号的分析与分解，也可以做时频图(Mirroring the empirical mode decomposition, analysis and decomposition of the signal can be achieved, but also can do the time-frequency diagram)

利用相关法进行系统辨识的matlab程序 包含m文件和simulink仿真图(System identification using the correlation method)

butterworth filter for images

仿真图是速度、距离、幅度三维图像，ICA（主分量分析）算法和程序，利用最小二乘算法实现对三维平面的拟合。( FIG simulation speed, distance, amplitude three-dimensional image, ICA (Principal Component Analysis) algorithm and procedures, Least-squares algorithm to fit a three-dimensional plane.)

扩展卡尔曼滤波算法是滤波领域较为重要的方法之一。本滤波算法是典型的卡尔曼滤波应用问题。(kalman filter is a verry important filter.EKF is a better filter.)

matlab的基本使用，通过它你会更好的学习matlab(matlab basic use, through which you will better learning matlab)
