Under Windows, you can use FEX: textinject.

A platform independent method is FEX: inputEmu. This is based on Java and explained on undocumented: gui-automation and undocumented automation-robot

thanks pal

well ,can you illustrate one easy program in MATLAB ...

my main program is in MATLAB and i want a way to make output as keyboard code of computer.

@Sasan: The shown links contain a full description of the usage of the Java Robot. The inputEmu is a Matlab wrapper for the Java Robot also and it contains enough help text. I'm surprised that Walter's short answer solves your problem already.

Answer 3

[Sasan Ardaneh]

import java.awt.AWTException;
import java.awt.Robot;
import java.awt.event.KeyEvent;
robot=Robot;
robot.keyPress(KeyEvent.VK_A);
robot.keyRelease(KeyEvent.VK_A);

[Walter Roberson]

Yes, that looks appropriate. I am pleased to see that you put in the keyRelease event, as it is common for people to think that only the keyPress is needed.
