java.io.IOException: CreateProcess: matlab error=2

[Jack]

I'm using matlab it is call by a class what its name is "Engine"

I'm working in linux and works fine, I want to know how can I do that with windows.
I found on Internet a class call MatlabControl, that uses all .jar of matlab.
But it gives to me problems when I try to create a matlab object

 try {
            Process p = Runtime.getRuntime().exec("matlab");
        } catch (IOException ex) {
            ex.printStackTrace();
        }

And this is the exception:

java.io.IOException: CreateProcess: matlab error=2
        at java.lang.ProcessImpl.create(Native Method)
        at java.lang.ProcessImpl.<init>(ProcessImpl.java:81)
        at java.lang.ProcessImpl.start(ProcessImpl.java:30)
        at java.lang.ProcessBuilder.start(ProcessBuilder.java:451)
        at java.lang.Runtime.exec(Runtime.java:591)

        at java.lang.Runtime.exec(Runtime.java:326)
        at matlab.Main.main(Main.java:32)

Can you help me?
