gps的matlab仿真工具包version3.01，函数和处理方法非常全，不错的gps开发仿真工具(gps the matlab simulation toolkit version3.01, function and processing method is very full, good development of simulation tools gps)

I have get wavelet matlab coding.

说明：  单目视觉程序 通过对摄像机进行简单标定求出世界坐标犀利图像坐标系转换的必要参数，进而实现对固定平面内物体的位置定位及长度测量。针对该方法的特点，本文选取了4个点为标定点.(Through the simple calibration of the camera, the necessary parameters of coordinate system transformation of the sharp world coordinate image are obtained, and then the location and length measurement of the object in the fixed plane are realized. According to the characteristics of this method, four points are selected as the calibration points)

这是有关matlab的编程，值得一看，呵呵呵呵呵呵呵呵(matlab)

4. 数字信道化抗干扰反正，首先数字信道化多相滤波，差值的倍数为信道数的两倍，再采用AGC技术抗干扰。(4 digital channel anti-jamming anyway, the first digital channel of the polyphase filter, the difference in multiples of twice the number of channels, and then using the AGC technology anti-jamming.)

在matlab中，利用全局阈值对图像进行图像分割，得到有用的区域(Global threshold image in matlab for image segmentation, get useful area)

说明：  采用matlab针对地震波反应谱进行转换(Seismic wave response spectrum converter)

直方图是用面积表示各组频数的多少，矩形的高度表示每一组的频数或频率，宽度则表示各组的组距，因此其高度与宽度均有意义。 程序提取了很多直方图所需要的参数特征，如均值、方差、偏度、峰度、能量和熵。 (Histogram is that each group size the number of frequency, the height of the rectangular frequency of each group said that the number or frequency, the width of that group from each group, so the significance of height and width of both. Extraction procedures need a lot of parameters histogram features, such as mean, variance, skewness, kurtosis, energy and entropy.)
