I need to execute commands other than IO commands while interfacing with arduino through MATLAB. In particular I need to measure correctly the current supply voltage to precisely convert the ADC values into voltage signals. The code for arduino is

long readVcc() {
  long result;
  // Read 1.1V reference against AVcc
  ADMUX = _BV(REFS0) | _BV(MUX3) | _BV(MUX2) | _BV(MUX1);
  delay(2); // Wait for Vref to settle
  ADCSRA |= _BV(ADSC); // Convert
  while (bit_is_set(ADCSRA,ADSC));
  result = ADCL;
  result |= ADCH<<8;
  result = 1126400L / result; // Back-calculate AVcc in mV
  return result;
}
void setup() {
  Serial.begin(9600);
}
void loop() {
  Serial.println( readVcc(), DEC );
  delay(1000);}

My main thrust is to somehow port the readVcc function so that I can execute it from MATLAB. Is this possible and if any guide is available for this is available, please link it. My main thrust is to execute a command like follows
