SYSTEM Call an External Program

Usage

The system function allows you to call an external program from within FreeMat, and capture the output. The syntax of the system function is

  y = system(cmd)

where cmd is the command to execute. The return array y is of type cell-array, where each entry in the array corresponds to a line from the output.

Example

Here is an example of calling the ls function (the list files function under Un*x-like operating system).

--> y = system('ls a*.m')
y = 
  <cell array> - size: [3 1]
 
Columns 1 to 1
 addtest2.m  
 addtest3.m  
 addtest.m  
--> y{1}
ans = 
  <string>  - size: [1 10]
 addtest2.m
