说明：  Kalman 滤波实际应用，对于初学者来说是一份非常好的学习参考资料，呵呵！(The practical application of Kalman filtering, for beginners is a very good learning references, Ha ha!)

对原始图像在水平方向和垂直方向与2个滤波器(低通、高通)相卷积，可以得到4块面积为原图像1/4的子图，分别为水平方向低频和垂直方向低频(HH)、水平方向低频和垂直方向高频(HG)、水平方向高频和垂直方向低频(GH)、水平方向高频和垂直方向高频(GG)。(The original image in the horizontal direction and vertical direction and two filters (low pass, high pass) with convolution, you can get the original image area of 4 1/4 graph, respectively, horizontal and vertical direction low frequency ( HH), horizontal and vertical high-frequency low-frequency (HG), horizontal and vertical high-frequency low-frequency (GH), horizontal and vertical high-frequency high-frequency (GG).)

本程序估计相干信号的DOA。当信源相干时，MUSIC不能处理，本程序利用了其他的DOA算法作为演示。(This procedure is estimated coherent signal DOA. When the source coherence time, MUSIC can not handle, use this program as a demonstration of other DOA algorithms.)

基于matlab的汽车制动系统和ABS系统的仿真，有5个.m后缀文件，可以完美运行。(Matlab simulation of automotive brake systems and ABS system based, there are five. M file extension, you can run perfectly.)

Aerospace Toolbox 1.0 and Aerospace Blockset 2.2 made it easier to model and simulate aircraft dynamics in Simulink.

power_turbine,matlab仿真文件,电力电子、功率电子控制方面很有价值，调试通过(aspects of power_turbine, matlab simulation files, power electronics, power electronics control valuable debugging through)
