模拟信号的数字传输系统 matlab PCM编译码技术(The analog signal of the digital transmission system)

由matlab的commet函数改编而来，在原来基础上新增控制质点运动速度的功能(The commet by the matlab function adapted from the original particle motion based on the new speed control function)

VB调用Matlab制作的COM组件实现二者混合编程，本文章主要介绍在MATLAB中编写com组件，为了检验结果的正确性，在工程地质中要用到这项技能。（郑重声明：本资料是借用张赛民老师的成果，张赛民老师为第一作者，未经允许，不得用于商业用途）(VB COM component calls made to achieve both Matlab programming mix, this article focuses on com components written in MATLAB, in order to verify the correctness of the results, in engineering geology to use this skill.
