稀疏均匀圆阵求根MUSIC算法,包含波束空间变换，映射及求跟MUSIC算法的实现(Solving sparse MUSIC algorithm for uniform circular array, including the beam-space transformation, mapping, and seek to achieve with the MUSIC algorithm)

autocorrelation and crosscorrelation ..... basic idea about those stuffs.........

direct torque documentation

matlab高通滤波器，可以直接在matlab上运行，显示(matlab high-pass filter can be run directly in matlab to show)

说明：  利用matlab实现的时频分析，很好，很强大！(Using matlab to achieve the time-frequency analysis, very good, very powerful!)

清华大学信号课程第二次实验，内容是基于傅立叶级数的信号分解以及双音频按键音合成(Tsinghua signal course the second experiment, the content is based on the Fourier series of two-tone signal decomposition and synthesis of key tone)

说明：  极限学习机（Extreme Learning Machine, ELM）是一类基于前馈神经网络（feedforward neuron network）的机器学习算法，(Extreme Learning Machine, ELM)

朱邦芬只保留电子-声子互作用算符 对角项，把非对角项作为微扰处理； 原则上，不同的电子态对应于不同的晶格平衡位置；通常计算固体的振动性质时，假定电子处于基态。 (Zhu bonfim retain only electronic- phonon interaction diagonal operator, the diagonal of the non-perturbative as processing in principle, different electronic states corresponding to different lattice equilibrium position usually calculate the vibration of the solid nature, it is assumed that e in the ground state.)

自己编写的稀疏阵列的matlab波束形成程序，可画出9阵元稀疏阵列的阵列方向图，以及相应阵列的排列示意图和同等数目阵元的均匀阵列的对比效果图(sparse array beamforming)

碰磨相关的非线性输出频率响应的处理程序，MATLAB应用，应该对做这方面研究的有用处。(Rubbing nonlinear output frequency response associated with the process, MATLAB applications should do research in this area useful.)
