unix

Purpose

Execute a UNIX command from MATLAB.

Synopsis

unix('command')
[status,output] = unix('command')

Description

unix('command') executes a UNIX operating system command. The statement returns the resulting status as an integer and the standard output in a string variable.

Examples

[s,w] = unix('who') returns s = 0 and, in w, a MATLAB string containing a list of users currently logged in.

s =
    0
          
w =

If the UNIX command fails, MATLAB returns a nonzero status value. For example, 

[s,w] = unix('why')
why: Command not found.
          
s =
    256
          
w =
    []
