Using Arduino Interfacing w/ Software on the Computer
1

int ledCount = 3;
int ledPins[] = { 11, 12, 13 };
int ledDelay = 1000;

void setup() {
for (int thisLed = 0; thisLed < ledCount; thisLed++) {
pinMode(ledPins[thisLed], OUTPUT);
}
}

void loop() {
for (int thisLed = 0; thisLed < ledCount-1; thisLed++) {
digitalWrite(ledPins[thisLed], HIGH);
delay(ledDelay);
digitalWrite(ledPins[thisLed], LOW);
}
for (int thisLed = ledCount-1; thisLed > 0; thisLed--) {
digitalWrite(ledPins[thisLed], HIGH);
delay(ledDelay);
digitalWrite(ledPins[thisLed], LOW);
}
}

You posted "the code" (badly, but you can go back and correct it) in your original post.
What are you asking for?
Should this be in the "Interfacing" section, or in "Gigs and collaborations"?

now what should i post and where ?

It sounds like you should be posting an offer to pay someone to write code for you, in Gigs and collaboration. Here, we're willing to help you understand the issues well enough to write the code yourself. But, it sounds like you have no clue about matlab and no interest in getting such a clue.
