send multiple serial data from arduino to matlab

Try

void setup() 
{
  // Start serial at 9600 baud
  Serial.begin(9600); 
}

    void loop() 
{
  // Read the input on analog pin 11 and 12:
  int sensorValue = analogRead(A11);
  int sensorValue2 = analogRead(A12);


  Serial.print(sensorValue);
  Serial.print(",");
  Serial.println(sensorValue2);
  
/* 
And you will send strings like: 
 10,20\n
 11,15\n
 100,255\n
where \n is line feed and I removed the text strings, which are not necessary IMHO.
.and so on .....
The MATLAB receiver code is yours, see below .. 
*/

 
}

I have no clue how it the code to receive data from a serial line looks like in Matlab. But this is a fragment I'm using Processing.

// Read serial data           
   while (myPort.available() > 0) { // New data? 
   char ch = myPort.readChar(); 
   if (ch >= '0' && ch <= '9') {
    value[arrayIndex] = (value[arrayIndex] * 10 + (ch - '0'));
   } else if (ch == ',') {
     arrayIndex++;
     kommaZahl++;
   } else if ( ch == '\n') {
     // Print results when in debugging mode       
     if (debug) {
       println(value[0]);
       println(value[1]);
     }

And you can easily check the results using the serial console in ARDUINO.
