Hi, I connected a stepper motor to arduino and this is the example script that I used:

include <Stepper.h>
const int stepsPerRevolution = 200;  // change this to fit the number of steps per revolution
                                   // for your motor
 // initialize the stepper library on pins 8 through 11:
 Stepper myStepper(stepsPerRevolution, 8,9,10,11);            
 void setup() {
  // set the speed at 60 rpm:
  myStepper.setSpeed(60);
  // initialize the serial port:
  Serial.begin(9600);
 }
 void loop() {
  // step one revolution  in one direction:
   Serial.println("clockwise");
  myStepper.step(stepsPerRevolution);
  delay(500);
   // step one revolution in the other direction:
  Serial.println("counterclockwise");
  myStepper.step(-stepsPerRevolution);
  delay(500); 
}

How can I 'translate' this script in matlab code? My problem is that I want to control the rotation of the stepper depending on a value computed in matlab, so should be great if I could control the stepper motor directly with matlab. I saw that already exists 'ARDUINO I\O Package' but that works only with arduino motor shield but I have 'ARDUINO UNO'. Can anyone help me please?
