Matcom是mathTools公司推出的一个能将M文件转化成相同功能C++代码的工具。相比Matlab自带的编译器Compiler，用Matcom转化代码要简单和方便得多。本文将结合作者编程经验，以VC6.0和Matcom为例，详细介绍如何利用Matcom进行VC与Matlab的联合编程。-Matcom is mathTools Company introduced a document can M into the same functional C code tool. Compared Matlab's own compiler Compiler, with Matcom into code should be simple and more convenient. In this paper the author programming experience, and Matcom VC6.0 example, details on how to use Matcom VC and Matlab for the joint program.
