Syntax

Description

[str](#mw%5F3696ad34-b9ba-4806-b8c9-b0c5c80b416c) = computer returns the computer type on which MATLAB® is running.

[archstr](#mw%5F84beda3f-a155-4825-a5b3-0a6f460525f3) = computer('arch') returns the system architecture. The mex command and standalone applications use this value to locate MATLAB library files.
