can someone help me convert arduino code to matlab code

const int sensorPin = A0; int sensorVal = 0; unsigned long pulseCounter = 0; unsigned long firstPulseStartTime = 0; unsigned long secondPulseStartTime = 0; unsigned long time_between_pulses = 0; const unsigned long refractoryPeriod = 300; const double minutes_in_milliseconds = 60000;

//When you have determined your threshold, declare your variable //right below this line. This will change from person to person. const double threshold = 0.33;

//small delay to change our sampling rate
//and stabilize our signal
