匈牙利算法的实现，比较简单，本人自己写，望大家赐教-Hungarian algorithm is simpler, I wrote it myself, hope everybody with us

PCM编解码源程序 很好的程序。谢谢大家进行参考。-PCM codec good source procedures. Thank you for your reference.

此程序得到一个声音用 matlab，然后离散，和做滤波， 然后得到从那功能和神经网络的分类和回传播。

CCITT G.711语音压缩算法 -CCITT G.711 voice compression algorithm

这个函数也要被melcepst函数调用，用来进行计算Mel倒谱系数。这个函数的作用是构造mel滤波器组。-This function must be melcepst function call is used to calculate Mel cepstral coefficients. The role of this function is to construct a mel filter bank.

FIR滤波器设计中往往是线性相位，但不是最小相位，所以它的零点有部分在单位圆外。把单位圆外的零点映射到单位圆内，构成最小相位滤波器。-FIR filter design is often the linear phase, but it is not minimum phase, so it has some of the zeros outside the unit circle. To zero outside the unit circle is mapped to the unit circle, the minimum-phase filter constituted.
