压缩采样算法

说明：  基于灰色预测，指数平滑预测的几个MATLAB程序，对于预测类问题的数学建模，可以说是必备程序。我的导师给我传的。 funesm1,2,3分别为一二三次指数平滑预测程序 fungry为灰色预测程序 funcoef为时间序列预测程序 pudn为广大的编程爱好者提供了一个交流的平台，我在此先谢谢网站的工作人员，我也会努力编出好的程序，一起同大家分享。(Based on Gray predicted that the number of exponential smoothing forecasts MATLAB procedures, issues for the prediction of the mathematical modeling, can be said to be an essential procedure. My mentor gave me spread. funesm1, 2,3 were 123 times procedures fungry exponential smoothing forecast procedures funcoef gray prediction for time series forecasting procedures for pudn programming for the majority of fans provided a platform for exchange, I would like to thank the site staff, I will strive for a good program, to share together.)

说明：  PCA-SIFT算法的实现，PCA-SIFT是对SIFT算法的改进，用PCA替代SIFT算法中的第四步，提高了效率，且准确率更高(PCA-SIFT algorithm implementation, PCA-SIFT SIFT algorithm is an improved SIFT algorithm with PCA instead of the fourth step, improve efficiency, and higher accuracy)

this code is usefull for communication engineering

扩频序列的误码率性能仿真程序，在matlab下运行(Sequence Spread Spectrum BER performance simulation program, run under Matlab)

说明：  说话人识别的matlab实现，供大家参考(tell the speaker s voice)

工件加工问题，本程序提供了工件加工问题的一般算法question1 question2 question3经过调试能成功运行(workpiece machining, the process of machining the general algorithm question1 question2 question3 after the successful operation Debugging)

计算机械振动烈度，由采集的振振动位移数据来求得可直接使用。 (Calculation of the mechanical vibration intensity, obtained by the vibration vibration displacement data collected can be used directly.)

matlab入门到精通，对初学者和高手都非常有用。(Entry to the proficient in matlab, is very useful for beginners and master.)

this is for bit plane mapping... it produces 7 outputs with bit plane....
