how could I read digital pin pulses from arduino in matlab?
I mean by writing readDigitalPin(a,'D4')
it shows just 0 or 1
but I want to read pulses from this pin which connected with the phase of increamental encoder

Digital pins only return values of 0 or 1. If you want to read voltage information from an incremental encoder it would have to be connected to an analog in pin and then you would have to use readVoltage.

Yeah, as far as I know MATLAB can't natively change the interrupt pins.
