str = computer
archstr = computer('arch')
[str,maxsize] =
computer
[str,maxsize,endian] = computer
str = computer returns the string str with the computer type on which MATLAB is running.
archstr = computer('arch') returns the string archstr which is used by the mex command -arch switch.
[str,maxsize] = computer returns the integer maxsize, the maximum number of elements allowed in an array with this version of MATLAB.
[str,maxsize,endian] = computer returns either 'L' for little-endian byte ordering or 'B' for big-endian byte ordering.
| Platform | Word Size | str | archstr | maxsize | endian | ispc | isunix | ismac |
|---|---|---|---|---|---|---|---|---|
32-bit | PCWIN | win32 | 2^31 - 1 | L | 1 | 0 | 0 | |
64-bit | PCWIN64 | win64 | 2^48 - 1 | L | 1 | 0 | 0 | |
32-bit | 2^31 - 1 | L | 0 | 1 | 0 | |||
64-bit | GLNXA64 | glnxa64 | 2^48 - 1 | L | 0 | 1 | 0 | |
Apple Macintosh® | 64-bit | MACI64 | maci64 | 2^48 - 1 | L | 0 | 1 | 1 |
In some cases, both 32-bit and 64-bit versions of MATLAB can run on the same platform. In this case, the value returned by computer reflects which of these is running. For example, if you run a 32-bit version of MATLAB on a Windows x64 platform, computer returns PCWIN, indicating that the 32-bit version is running. You can get this information and the value of archstr from the Help menu, as described in Information About your Installation in the Desktop Tools and Development Environment documentation.
