matlab出错信息的技术，可以帮助我们快速找到出错的原因，提高编程效率。(matlab error information technology that can help us quickly find the wrong reasons, to improve programming efficiency.)

用周期图法求解功率谱曲线，并搜索信号频率值(Periodogram method for solving the power spectrum curve, and search for the signal frequency value)

寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)

一个应用于做人脸识别之前，对人脸来提取特征点的，带方向的滤波操作(wld is a filter to extract the important features from face image.)

说明：  变分模态分解方法能够使一个多频带的故障信号，分解出具有单个频带的子信号，然后使用共振解调方法可实现故障信号的诊断。(VMD method can decompose a multi band fault signal into a single band sub signal, and then use resonance demodulation method to realize fault signal diagnosis.)
