TIME-FREQUENCY

关于棋盘格的角点提取，用MATLAB编写的(Checkerboard on the corner extraction, prepared by using MATLAB)

产生零均值单位方差高斯白噪声的1000个样点,估计随机过程的自相关序列(units have zero mean Gaussian white noise variance to the 1,000-point, it is estimated that the random process autocorrelation sequence)

MATLAB 灰度世界法白平衡处理，在全局白平衡中得到广泛应用，特点是能够利用更多的图像信息来做判断(MATLAB gray world white balance processing method has been widely used in the global balance, the feature is the ability to use more image information to do judgment)

本文件仿真有关LCL滤波器的伯德图，希望大家一起学习。仿真并不是很全面，没有把所有的情况都考虑在内，但是提供了一个仿真的思路。(This document the simulation about the bode plots of the LCL filter, hope we learn together. Simulation is not very comprehensive, not all things into consideration, but provides a simulation of train of thought. )

基于卡尔曼滤波的机动目标跟踪VD算法，变维滤波的原理和性能(Based on Kalman Filter VD maneuvering target tracking algorithm, variable dimension filtering principle and performance)

绘制任何阵列天线的三维方向图,input_sideline16是一个16单元的线阵，里面是各个单元的位置、幅度、相位信息，先运行这个文件，再运行UNtitle5，就可以画出其二维、三维方向图；同理，自己可以写出任何阵列的信息，然后用UNtitle5画出其方向图。(draw the pattern of the antenna)

Matlab讲义高级.rar，PPT课件(Matlab senior notes. Rar, PPT Courseware)

The purpose of this program is to calculate the refractive index of a certain material. And you should import some basic optical parameters firstly.
