matlab高级编程 课本中的源代码 作者谷源涛(" Matlab Advanced Programming," in the source code for textbook authors Gu Yuan Tao)

说明：  kalman滤波，比较当过程噪声协方差Q和测量噪声协方差R取不用值时对卡尔曼滤波效果的影响(primary kalman filter.it shows how different R and Q aspect the reslut of kalman filter)

FT3 M-file for ft3.fig FT3, by itself, creates a new FT3 or raises the existing singleton

The attached source code is the implemenation of acoustic echo canceller and noise reduction.

计算信号相关性的传统方法，利用卷积来计算。(The traditional calculation of signal correlation methods, the use of convolution calculation.)

说明：  研究高超声速飞行器在纵向的运动情况，对系统的速度和飞行高度进行仿真分析，我们将对在不同的 、 值的条件下分析出系统的最优性能(The longitudinal motion of the hypersonic vehicle is studied, and the system speed and flight height are simulated. We will analyze the optimal performance of the system under different conditions and values.)

说明：  该程序介绍Matlab时频分析技术及其应用，利用该程序可以分析周期信息(This program is used to get the frequence. )

RBB image extraction and some image processing function on each image channel

这是一个不错的资料是关于cdt2000模块的资料可以通过资料查询很多关于这个模块的知识(This is a good information regarding cdt2000 module information through data queries can be a lot of knowledge on this module)

我们设计低通数字滤波器并选择窗函数确定频率响应。(We design a digital low pass filter and the choice of window function to determine the frequency response. )
