什么是MCR？
MCR之前是 matlab component runtime的缩写，后更名为 matlab compiler runtime。MCR实际上是一组独立的共享库，也即是常说的动态连接库，所起的作用是使得你可以执行编译过的matlab文件，与matlab提供的另外两个库----数学库和图形库不同之处在于它支持matlab语言所有的特性，而不仅仅是数学计算和图形功能。换句话说他的作用就是给编译后的matlab文件执行提供一个环境。
matlab帮助系统对MCR的介绍
The MCR is an engine for execution of compiled MATLAB code.As such, when a compiled application runs, there is sometimes a delayas the MCR is initialized. There can be a delay the first time yourun the application,
although typically less than you experience runningon the MATLAB desktop.
MATLAB Compiler RuntimeMATLAB Compiler 4 uses the new MATLAB Compiler Runtime (MCR), which is a standalone set of shared libraries that enable the execution of compiled MATLAB files, instead of the
MATLAB C/C++ Math and Graphics Libraries. The MCR provides complete support for all features of the MATLAB language.
