MATLAB analyzes OS-specific path

I am launching a MATLAB project that is used by several users, some of whom are running Windows and some running Linux.

In some scenarios, I need to access files that are in external directories and which I do not want to add to the MATLAB path.

To host both Linux and Windows, I need to determine the type of operating system that I am running and set the directory separator accordingly ('\' for Windows, '/' for Linux).

I tried

os = getenv('OS')

(which I saw in some official manual), but it returns an empty string.

I could check the first “pwd” character, but it's pretty ugly, and I expect there should be something simpler.

Thanks for any suggestions!

To use the correct directory separator, you do not need to write code to work with various operating systems. filesepprovides the correct directory separator.

My1stDir = 'Year2012';
My2ndDir = 'Feb';
My3rdDir = 'Day03';

MyDir = [ 'mydata', filesep, My1stDir, filesep, My2ndDir, filesep, My3rdDir ];

On Linux, you get:

MyDir =
     mydata/Year2012/Feb/Day03

On Windows, you will get:

MyDir =
     mydata\Year2012\Feb\Day03
