matlab图像处理基础，都是一些比较基础的东西，希望对有需要的同学有用(matlab image processing based)

灰度共生矩matlab代码。。。。。。。。(Gray symbiotic moments matlab code. . . . . . . .)

matlab仿真线性雷达天线方向图。仿真矩形天线的方向图。(The matlab simulation linear radar antenna pattern. The simulation of rectangular antenna pattern. )

是自适应阈值的分割，主要对图像用matlab进行分割图像，确定图像想要的东西(Adaptive segmentation threshold, the main image to image segmentation using matlab, determine what image you want)

基于matlab的声音特征提取，可用于语音识别和声纹识别(Matlab-based audio feature extraction, can be used for speech recognition voiceprint recognition)

说明：  捷联惯导系统放置在室内测试台上做静态测试，测试时间4500s。 1）取前180数据做粗对准（解析对准法）； 2）取第181s~900s数据做精对准（Kalman滤波法）； 3）从第901s开始做纯惯导解算； 4）用国军标的导航系统位置精度评价方法评估系统定位精度（分别计算CEP50 和 CEP95 下的定位精度）。(The strapdown inertial navigation system was placed on the indoor test bench for static test with a test time of 4500s. 1) take the first 180 data for rough alignment (analytical alignment method); 2) accurate alignment of 181s-900s data (Kalman filtering method); 3) pure inertial navigation solution is performed from 901s; 4) the positioning accuracy of the navigation system is evaluated by the method of position accuracy evaluation of the national military standard (the positioning accuracy under CEP50 and CEP95 are calculated respectively).)

永磁同步电机的直接转矩控制matlab/simulink模型，可用。效果不错。(matlab/simulink model of PMSM DTC method。)
