How do you open PDF file in MATLAB on a Linux platform?

I ported MATLAB code from Windows 7 to CentOS Linux. The "open(<pdf file path name>);" statement that works fine on a Windows platform didn't work on the Linux platform. I can double click on the PDF file in the CentOS File Browser and it immediately open in a PDF reader. The path is correct and there is no exception thrown. I gave it a bad file name and got a file not found exception.

If anybody is interested, the MATLAB open doesn't appear to support PDF files in Linux. I ended up using the CentOS Linux command "evince". Other flavors of Linux may have another command to open PDF files.

    if isunix
        system(['evince ' help_file_name ' &']);
    elseif ispc
        open(help_file_name);
    else
        msgbox(['Open ' help_file_name 'in the operating system'],'Product Help');
    end
