基于MATLAB的数据采集系统的研究

由于MATLAB不能直接对硬件端口进行读写操作，缺乏了实时性，使得工程上的应用受到了极大的限制。而通过MATLAB应用程序接口Mex调用C++语言，可实现在MATLAB环境下对硬件端口信号的读写。为此，笔者对Mex接口文件进行了详细介绍，包括Mex接口的各种特殊功能、详细编写规则和具体编译要求，具体阐述了Mex接口在MATLAB环境下的调用及使用。并根据Mex接口的相关功能，对MATLAB数据采集系统的设计在理论上进行了探讨，以图对MATLAB功能进行进一步的扩展。

Research on Data-Collection System Based on MATLAB

Since MATLAB can not write directly to hardware available for operation,and it lacks of a real-time,it works on the applications has been significantly hampered.MATLAB applications through redeployment C language interface Mex,Achievable in the MATLAB environment for the specific hardware interface signals.Therefore,author of a paper details Mex interfaces,including interfaces Mex various special functions,and specific translation rules for the preparation of detailed,enunciated the transfer and the use of Mex interface in the MATLAB environment.And in accordance with the relevant functional interface Mex,MATLAB data acquisition system for the design in theory explored in a bid to further expand the functions of MATLAB.
