Re: external processes

Hello,

I just tried the ExecRunner class with a compliation of a Matlab skript. 
My parameters are Matlab matrices and vectors like
[1 2 3; 4 5 6]
and so on. In the ExecRunner class this 2x3 matrix will be destroyed by 
the StringTokenizer and my Matlab skript will be started with the arguments
[1, 2, 3;, 4, 5, 6]
which doesn't make any sense. I would like to suggest to add a method 
where one can pass the aruments as a String[]-vector. In my case I could 
pass every single Matlab matrix and every Matlab vector as a single 
String. I just tried this out with the following code:

  public static String execute(String command[]) throws IOException {
    String out = null, temp;
    Process exe = Runtime.getRuntime().exec(command);
    BufferedReader in = new BufferedReader(
      new InputStreamReader(exe.getInputStream()));
    for (out = ""; (temp = in.readLine()) != null; out += temp + "\n");
    return out; 
  }

It works fine. I would add something similar to the class ExecRunner 
mentioned above, but adapted so that the other features of this class 
will also be maintained.
