经验模态分解(EMD)的Matlab程序包(Empirical Mode Decomposition (EMD) of the Matlab package)

本文借助于矩阵对的标准相关分解(CCD)技术,给出了问题P的通解表示 并且得到了矩阵方程有解的一个充要条件. (THE LEAST-SQUARE SOLUTIONS OF A MATRIX EQUATION )

染色体识别与统计,识别其中的染色体并统计其数目，我们采用Matlab平台提供的一些图像处理函数.(Chromosome identification and statistics, to identify the chromosome and the number of statistics, we have adopted a Matlab platform provides a number of image processing functions.)

利用matlab编程实现偏最小二乘算法，可完成辨识模型的参数(partial least square)

ISM算法示例，基本能用，还有问题，欢迎讨论(ISM algorithm for example, the basic use, there are questions, please discuss)

假定半波长间隔均匀分布线列布阵的阵元数N=16，若入射平面波为f=62.5Hz的正弦信号，信号持续时间为0.4s， 系统采样频率 =1 KHz,阵列加权为均匀加权，分别给出 a)当平面波信号分别从 0,10,20,30,40,50,60,70,80,90,100度方向入射时，指向90度的波束形成器的输出序列； b)当平面波信号分别从0:1:180度方向入射时，指向90度的波束形成器的输出序列经过平方求和后的分贝数输出（把所有181个输出绘制在同一幅图中)(Assuming N=16, f=62.5, fs=1KHz, uniform weight, and the code gives: a) 90 degree response when incidence angles are: 0: 10: 100 degrees b) 90 degree spectral response when incidence angles are: 0:1:180 degrees )

局部频谱细化算法的实时效率 比较zoom-fft各种算法(Local spectrum thinning algorithm more efficient, real-time zoom-fft algorithms)

信号时域采样,频域进行频谱分析matlab，适合初学者。(signal analytic)

matlab gui 资料学习,非常值得一看，word版(matlab gui reference)

说明：  实现了卷积码的viterbi译码，软判决和硬判决均可实现，是从英文教学书上抄下来的。(Achieved viterbi decoding of convolutional codes, soft decision and hard decision can be realized, from the English teaching books, copied down.)
