说明： MUSIC算法
DOA（Direction Of Arrival）波达方向定位技术主要有ARMA谱分析、最大似然法、熵谱分析法和特征分解法，特征分解法主要有MUSIC算法、ESPRIT算法WSF算法等。
MUSIC (Multiple Signal Classification)算法，即多信号分类算法，由Schmidt等人于1979年提出。MUSIC算法是一种基于子空间分解的算法，它利用信号子空间和噪声子空间的正交性，构建空间谱函数，通过谱峰搜索，估计信号的参数。对于声源定位来说，需要估计信号的DOA。MUSIC算法对DOA的估计有很高的分辨率，且对麦克风阵列的形状没有特殊要求，因此应用十分广泛。(DOA (direction of arrival) positioning technology mainly includes spectrum analysis, maximum likelihood method, entropy spectrum analysis method and feature decomposition method. The feature decomposition method mainly includes music algorithm, ESPRIT algorithm, algorithm, etc.
Music (multiple signal classification) algorithm, namely multi signal classification algorithm, was proposed by Schmidt In 1979. MUSIC algorithm is an algorithm based on subspace decomposition. It uses the orthogonality of signal subspace and noise subspace to construct spatial spectrum function, and estimates signal parameters through spectrum peak search. For sound source localization, DOA of signal needs to be estimated. MUSIC algorithm has high resolution for DOA estimation, and has no special requirements for the shape of microphone array, so it is widely used.)

electromagneticwaveTE13
利用matlab仿真金属圆柱体内电磁波分布，有助于掌握电磁波的传播情况。
把程序文档放入matlab的默认读取文档中，打开Cwave.m。Cwave.m是演示程序，由它调用其它函数。其中Z表示Kz*z，范围为0~2*pi。默认取2*pi为一个周期，num表示在一个周期内平均取多少个Kz*z值，默认为50(计算后每个值如Er都有五十幅图)。CWaveGuideCaculate函数用于计算Er,Efia,Hr,Hfia,Hz等值。CWaveGuideShow用于三维显示计算后得到的值，可以比较生动看到在一个周期内计算量的一连串的变换。(Matlab simulation using electromagnetic wave distribution inside the metal cylinder, is useful in the propagation of electromagnetic waves. To process the document read into matlab' s default document, open the Cwave.m. Cwave.m is the demonstration program, which will call other functions. Where Z said Kz* z, the range of 0 ~ 2* pi. The default access for a period of 2* pi, num, said the average take in a cycle number of Kz* z, default is 50 (calculated as per the value of Er has 50 chart). CWaveGuideCaculate function is used to calculate Er, Efia, Hr, Hfia, Hz equivalent. CWaveGuideShow been calculated for three-dimensional display of values, can be seen more vividly in a cycle of computation of a series of transformations.)
