detectOS

detectOS returns the name and version number of the operating system.

Purpose

For the development of cross-platform apps in MATLAB, it is useful to know the operating system (OS) on which MATLAB is running, e.g. to select native fonts and font sizes (see getOSfont) or to fine-tune the layout and design of graphical user interface elements. detectOS returns the name and version number of the underlying OS for a wide range of platforms and OS versions.

Usage

OS = detectOS returns the name of the operating system as a lowercase character vector, such as 'windows', 'macos' (which includes OS X), 'solaris', 'aix', 'ubuntu', 'centos', and many other Unix/Linux distributions. It is thus much more fine-grained than MATLAB's built-in ispc / ismac / isunix and computer functions. If the OS cannot be determined, an error is thrown.

[OS, OSVersion] = detectOS also returns the OS version number as a numeric row vector. For example, Windows 7 SP1 (version 6.1.7601) is reported as OS = 'windows' and OSVersion = [6, 1, 7601]. If the OS version cannot be determined, a warning is issued and the empty numeric array is returned.

Requirements

detectOS is compatible with MATLAB R2016b and later releases (version 1.0 iscompatible with R2013a and later releases). It was tested on the following operating systems (64-bit, unless otherwise stated) and should run on a wide variety of other Unix/Linux distributions without any modification:

  • Windows 10 (10.0.10586)
  • Windows 8.1 Update 1 (6.3.9600)
  • Windows 7 (6.1.7601)
  • Windows 7 (6.1.7601), 32-bit
  • Windows XP Pro SP3 (5.1.2600),32-bit
  • macOS Big Sur (11.2.3)
  • macOS Catalina (10.15.7)
  • macOS Sierra (10.12.1)
  • OS X El Capitan (10.11.6)
  • Ubuntu 16.04 LTS
  • Ubuntu 15.10
  • Ubuntu 14.04 LTS
  • CentOS 7
  • CentOS 6.8 (Final)

Motivation

Another great tool returning information about the CPU and operating system is CPU Info. Unfortunately, CPU Info does not differentiate between Unix/Linux distributions, and does not return sensible information about the OS version in these cases. Adding this capability was the main motivation for developing detectOS.

Feedback

Please let me know if you have tested detectOS on other operating systems. Any feedback or suggestions for improvement are welcome!
