这里提供了两个消除趋势相的matlab程序 在故障诊断中 要对信号进行频谱分析 而在频谱分析前要消除趋势相 这样得到的频谱 能更好的反映故障 有利于进一步诊断(Here are two trends in the elimination phase of the matlab program in fault diagnosis to the signal spectrum analysis and spectrum analysis in the former to eliminate the tendency of such spectrum can be better reflected further in favor of fault diagnosis)

觉得很好的一个Matlab论文想和大家一起分享，互相学习。(Find a good paper would like Matlab to share with everyone, learn from each other.)

PCA算法。PCA的目的是找到能够分离出最大方差的方向，所以首先求原来所有数据三个维度上的协方差，然后求这个协方差的特征值，最大特征值为第一个方向，从此以此类推。(PCA algorithm. The purpose of PCA is to find able to isolate the direction of maximum variance, so first find all the data in three dimensions on the original covariance, and then find the eigenvalues ​ ​ of the covariance, the biggest feature is the first in one direction, from and so on.)

matlab实现用语音信号作为调至信号的幅度调制和频率调制，以及解调。(Matlab implements amplitude modulation and frequency modulation using speech signals as modulation signals, and demodulation.)

利用一個統計方法，可以設定感應器資料與流程，設定行為流程後，可以再透過統計寄送出使用者行為！(Use a statistical method, you can set the sensor data and processes to set the behavior of processes can be sent through statistical user behavior.)
