Arduino with Matlab. Need some assistance.

Hi there, this is my first time trying to run Arduino with Matlab. Also I'm not that good with Matlab. So, I got this Arduino code to try and run 2 DC motors:

int motor_left[] = {
4, 5, 10};
int motor_right[] = {
2, 3, 9};
int ledPin =  13; 

 void setup()
{

int i;
for(i = 0; i < 2; i++){
  pinMode(motor_left[i], OUTPUT);
  pinMode(motor_right[i], OUTPUT);
  pinMode(ledPin, OUTPUT);
}
}

 void loop()
{
        drive_forward();
        delay(500);
        motor_stop();

        drive_backward();
        delay(500);
        motor_stop();

}

 void motor_stop(){
  digitalWrite(motor_left[0], LOW);
  digitalWrite(motor_left[1], LOW);

digitalWrite(motor_right[0], LOW);
digitalWrite(motor_right[1], LOW);
delay(25);
}

 void drive_forward(){
  digitalWrite(motor_left[0], HIGH);
  digitalWrite(motor_left[1], LOW);

digitalWrite(motor_right[0], HIGH);
digitalWrite(motor_right[1], LOW);
}

 void drive_backward(){
  digitalWrite(motor_left[0], LOW);
  digitalWrite(motor_left[1], HIGH);

digitalWrite(motor_right[0], LOW);
digitalWrite(motor_right[1], HIGH);
}

Now when I try to run this code in Matlab, it causes some error like this:

 Error: File: motor.m Line: 9 Column: 3
 Illegal use of reserved keyword "for".

So maybe I thought that I need to translate the Arduino code into Matlab code.

This is the one that I used in Matlab:

 a=arduino == ('COM14')

 int motor_left[] == { 4, 5, 10};
 int motor_right[] == { 2, 3, 9};
 int ledPin =  13; 

 void setup()
{int i;
  for(i = 0; 1i < 2; i++){
    pinMode(motor_left[i], OUTPUT);
    pinMode(motor_right[i], OUTPUT);
    pinMode(ledPin, OUTPUT);}
 }
 void loop()
{       drive_forward();
        delay(500);
        motor_stop();

        drive_backward();
        delay(500);
        motor_stop();       
}
 void motor_stop(){
  digitalWrite(motor_left[0], LOW);
  digitalWrite(motor_left[1], LOW);

digitalWrite(motor_right[0], LOW);
digitalWrite(motor_right[1], LOW);
delay(25);
}
void drive_forward(){
digitalWrite(motor_left[0], HIGH);
digitalWrite(motor_left[1], LOW);

digitalWrite(motor_right[0], HIGH);
digitalWrite(motor_right[1], LOW);
}
void drive_backward(){
digitalWrite(motor_left[0], LOW);
digitalWrite(motor_left[1], HIGH);

digitalWrite(motor_right[0], LOW);
digitalWrite(motor_right[1], HIGH);
}
void turn_left(){
digitalWrite(motor_left[0], LOW);
digitalWrite(motor_left[1], HIGH);

digitalWrite(motor_right[0], HIGH);
digitalWrite(motor_right[1], LOW);
}
void turn_right(){
digitalWrite(motor_left[0], HIGH);
digitalWrite(motor_left[1], LOW);

digitalWrite(motor_right[0], LOW);
digitalWrite(motor_right[1], HIGH);
}

The code you have is not MATLAB code, it is C code. You cannot run it in MATLAB. It needs to be compiled by a C compiler that is appropriate for the Arduino and loaded into the device.
