说明：  对信号进行EEMD分解，程序已调通，欢迎下载。有问题请留言(EEMD decomposition of signals)

编写语法分析程序，实现对算术表达式的语法分析。要求所分析算数表达式由如下的文法产生： E->E+T|E-T|T T->T*F|T/F|F F->id|(E)|num-Write parser to achieve parsing of arithmetic expressions. Requirements analysis arithmetic expressions generated by the following grammar: E-> E+ T | ET | T T-> T* F | T/F | F F-> id | (E) | num

说明：  i2c 测试demo，适用于i2c调试，可以适用示波器测量波形确认i2c是否通。(I2C test demo, suitable for I2C debugging, can be applied to oscilloscope measurement waveform to confirm whether I2C is passable.)

说明：  BCI的2003年竞赛数据,p300的全部竞赛数据!(BCI's 2003 competition data, P300's all contest data!)

说明：  雷达信号处理中相参积累，生成线性调频程序，加噪声，形成回波，进行数字下变频， 抽取，再通过匹配滤波器，进行相参积累，非常完整的程序(In radar signal processing, coherent accumulation generates LFM program, adds noise, forms echo, performs digital down conversion, extraction, and then conducts coherent accumulation through matched filter, which is a very complete program.)

在频域中组合空间域和局部相位量化（LPQ）的局部二进制模式（LBP）用于面部识别。 首先，从LBP特征和频域中提取人脸图像以提取LPQ特征，然后合并到LBP / LPQ直方图中以比较直方图相似度。 最后，使用最近邻原则来识别。 在YALE和AR标准人脸数据库上的实验表明，该方法获得的结果优于单一方法。(A local binary pattern (LBP) combining spatial domain and local phase quantization (LPQ) in frequency domain for face recognition. Firstly, the face image is extracted from the LBP feature and the frequency domain to extract the LPQ feature, and then merged into the LBP /LPQ histogram to compare the histogram similarity. Finally, the nearest neighbor principle is used to identify. Experiments on the YALE and AR standard face databases show that the results obtained by this method are better than the single method.)
