Now I have a long int array including some short array such beginning with 55 and ending 00, whose length was 10, but the contents between 55 and 00 could not be recognized for they were send from serial port. How could I extract those short arrays from the long array? Thanks!

How are you doing the reading from the text file? The details might matter.

as_short = typecast(YourLongArray, 'uint16');
sub_pos = find(as_short(1:end-9) == 55 & as_short(10:end) == 0);
short_array = as_short(sub_pos:sub_pos+9);

You would normally need to write a protocol that triggers the mcu to send data, instead of just immediately sending it.
Perhaps you were thinking that when the MCU opens its serial port that the MCU would then wait untl MATLAB opens the serial port on its side before the MCU would proceed to send the data. It is possible to program serial ports that way, but it is not typically done on instruments.
