MAT文件是MATLAB使用的一种二进制数据文件,MAT文件可以包含一个或者多个MATLAB变量。MAT文件不仅保存各变量数据本身,它同时保存变量名以及数据类型等。所以在MATLAB中载入某个MAT文件后,可以在当前MATLAB工作空间完全再现当初保存该MAT文件时的那些变量。这是MAT文件优于其他文件格式的一个原因。 | |
在MATLAB环境中,通常使用load和save两个命令进行MAT文件的读和写。这两个命令在默认情况下以MAT文件格式处理文件,但是也可以用-ascii参数选项来强制以文本方式处理文件,但一般不使用。 | |
MEX文件是按一定格式,使用C语言或Fortran语言编写,由MATLAB解释器自动调用并执行的动态链接库(Dynamic Link Library,DLL)函数。在Windows系统中,这种文件类型的后缀名为.dll。 | |
MEX文件的使用极为方便,只需在MATLAB命令提示符下输入MEX文件名即可,这与MATLAB内在函数的调用方式完全相同。当用户执行一个MEX文件时,MATLAB系统将首先搜索MATLAB系统的所有可搜索路径,然后载入并执行第一个与用户输入的文件名相匹配的可执行文件。因此,在MATLAB中存在两种类型的可执行文件:MEX文件和M文件。 | |
