在32或64位matlab上运行？

Question

如何确定我是在32位还是64位版本的matlab上运行？

我有一些预编译的mex文件需要不同的路径,具体取决于32/64bit matlab.

Answer 1

32对64位的问题实际上是一个红色的鲱鱼.如果我理解正确,您需要确定需要哪组已编译的MEX文件,以便您可以适当地设置路径.为此,您可以使用以下功能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.

Answer 2

接受ScottieT812和dwj建议,我发布自己的解决方案以获得一些积分.

该函数computer返回我正在运行的体系结构.所以:

switch computer
    case 'GLNX86'
        display('32-bit stuff')
    case 'GLNXA64'
        display('64-bit stuff')
    otherwise
        display('Not supported')
end
