用粒子群算法解决线性以及非线性的参数寻优过程，算法程序简单但是效果较好，很好解决了蚁群算法的某个参数的寻优效果不好的情况

该函数用于读取ecg信号，找到小波变换模极大序列(function to read the signals ecg find wavelet transform modulus maxima sequence)

根据陈燕生《液体动静压轴承》编写的有回油槽径向静压轴承的程序，可显示承载能力、压强、刚度及温升等图谱(According to Chen Yansheng " liquid hybrid bearing," have written back to the tank radial hydrostatic bearing program, you can display the carrying capacity, pressure, stiffness and temperature profiles, etc.)

通过特征矩阵，标签矩阵，将节点通过它们之间的相互联系，构成graph,并求取它的邻接矩阵(Through the characteristic matrix and label matrix, the nodes are connected with each other to form a graph, and its adjacency matrix is obtained.)

模式分类工具箱，SVC,PCA等,核分类，带例子以及所需数据(PatternClassificationToolBox，PCA,quadrat,kernels,bayes)

给出了信号压缩通常的变换-量化-编码函数。DHT函数为离散DHT变换，是FFT变换的近似，其正反变换相同，克服了FFT复系数不利于存储的缺点。LLMAX函数给出了某x序列在固定比特下的最佳量化输出。熵编码函数为霍夫曼编码。(Gives the signal compression usually transform- quantitative- coding function. DHT DHT discrete transform function, the FFT transform approximation, the same positive and negative transformation, overcoming complex FFT coefficient is not conducive to storage shortcomings. LLMAX function x is given a fixed bit sequence in the optimum quantized output. Entropy coding function as Huffman coding.)
