说明：  简单易懂的A-Law（13-segment) PCM的源代码,encode 的过程，适合初学者(Easy-to-read A-Law (13-segment) PCM source code, encode process, suitable for beginners)

此程序主要功能是 1 画出标准零阶贝塞尔函数， 2 在估计多普勒时，接收信号的实部或者虚部的自相关函数接近于贝塞尔函数，所以画出了一条接近于贝塞尔函数的曲线图(The main function of this program is 1 shows the standard zero-order Bessel function, 2 estimate the Doppler, the autocorrelation function of the received signal or the imaginary portion of the real part close to the Bessel function, so to draw a graph of the Bessel function is close to)

基本的粒子群算法以及使用具有量子行为的粒子群算法，能够很好的用于全局的寻优(The basic particle swarm optimization and the use of a quantum particle swarm behavior can be very good for the overall optimization)

适用于线列阵的常用定位算法，包括CBF,MVDR以及MUSIC(applicable to common line array positioning algorithm, including CBF, and MVDR MUSIC)

是在时域上做相关，直接用covn做相关，计算量比较大，估计比较明显。(Is done in the time domain correlation and directly related with covn, calculate than the larger, more obvious estimate.)

介绍了一些函数插值方面的方法，主要用于通过matlab实验函数逼近打基础，(Some function interpolation method is mainly used for laying the foundation by matlab experimental function approximation)

纹理合成，利用Matlab开发平台 ，实现小块纹理的快速合成(Texture synthesis)
