近场MUSIC算法，利用多重信号分类方法把位于近场的声源信号进行方位估计。(Near-field MUSIC algorithm, the use of multiple signal classification method put field is located near the sound source signal DOA estimation.)

说明：  单天线联合检测算法的matlab仿真源程序——场景：基站和1用户单天线，TD下行(Single-antenna co-detection algorithm of matlab simulation source code- the scene: the base station and a user single-antenna, TD downlink)

MUSIC 算法的原程序,希望对大家有帮助(the original procedure, we hope to help)

模态分析，获得采样数据的固有频率、各阶振型，阻尼比等，(Modal analysis, the natural frequency of the sampling data, each vibration mode damping ratio)

蚁群算法路径规划matlab代码，可以正常运行(Ant colony algorithm for path planning of the matlab code, and can run normally)

this matlab code denoise the pink noise from pcg signal and generate the specogram

说明：  用Matlab快速求斜率，方法简单易行，程序条理可靠。(无)

说明：  matlab数值编程使得数值计算工作量大大减轻，但是由于它其实是一种解释语言，而且没有国际标准，另外也没法在没有安装matlab的计算机上运行，不能用于计算密集型应用场合，极大地限制了它地应用，主要应用于物理，数学和化学，部分工程应用领域的计算工作量小的科技工作者。计算工作量大的工作，如流体力学求解，虽然matlab有解偏微分方程组的方法，但那几乎是用来作为例子来说明的，换句话说，只能作为上课例子。大型流体力学计算是计算密集型的一个例子，需要高效运算程序或并行化处理。 (chao liu ji suan)

Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, Compact Discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps. Quantization Noise occurs in PCM.

用于转子故障振动，采集信号后，用小波包方法对振动信号进行频谱分析，比傅立叶变换更细化。(Spectrum analysis of vibration signal by wavelet packet method)
