matlab - 在 32 位或 64 位 matlab 上运行？

Question

如何确定我运行的是 32 位还是 64 位版本的 matlab？

我有一些预编译的 mex 文件，它们需要不同的路径，具体取决于 32/64 位 matlab。

Answer 1

32 位与 64 位的问题实际上是转移注意力。如果我理解正确的话，您想确定需要哪一组编译的 MEX 文件，以便您可以适本地设置路径。为此，您可以使用函数 mexext:

>> help mexext
 MEXEXT MEX filename extension for this platform, or all platforms. 
    EXT = MEXEXT returns the MEX-file name extension for the current
    platform. 

    ALLEXT = MEXEXT('all') returns a struct with fields 'arch' and 'ext' 
    describing MEX-file name extensions for all platforms.

    There is a script named mexext.bat on Windows and mexext.sh on UNIX
    that is intended to be used outside MATLAB in makefiles or scripts. Use
    that script instead of explicitly specifying the MEX-file extension in
    a makefile or script. The script is located in $MATLAB\bin.

    See also MEX, MEXDEBUG.
