matlab檔案，用於轉檔用途，轉成kml以google earth開啟，輸入nmea檔案，轉換成kml檔案輸出(convert kml file)

matlab 中基于互相关函数的程序，希望对各位学者有帮助！(matlab cross correlation function based on the procedure, in the hope that scholars will help you!)

关于信号处理中傅立叶变换的MATLAB函数，可以与FFT进行对比，运算速度比较快。(on Signal Processing Fourier transform function MATLAB, compared with the FFT. Operational speed is faster.)

为保证轧机生产线安全、高效工作，及时掌握电气、机械设备的工作状态和潜在事故信息，建立了以振动、电量参数为主的在线监测诊断系统。系统实时采集的大量数据，为设备管理与维护及故障诊断提供了重要依据(Rolling mill production line in order to ensure safe, efficient work, timely information on electrical, mechanical equipment, working condition and potential accident information, set up a vibration, power consumption parameters based online monitoring and diagnosis system. System real-time acquisition of large amounts of data, for equipment management and maintenance and fault diagnosis provides an important basis for)

应用hough变换检测圆的代码，很方便。(Hough transform circle detection application of the code, very convenient.)

说明：  可就在三个错误的bch码，以及经过仿真在不同SNR下的误码率曲线。我们的业余作业。经过调试的。(This is my homework on 3-error-correcting bch code and its bit error rate curves at different SNR after debugging.)

基于MATLAB和电子表格共同的有限元程序。电子表格进行前处理，MATLAB读入进行计算及后处理。(Based on MATLAB and Spreadsheets a common finite element program. Before dealing with spreadsheets, MATLAB reads the calculation and post-processing.)

说明：  无线传感网络节点定位算法的研究，使用chan算法(Wireless sensor node localization algorithm, the use of chan algorithm)
