The problem of delay in contact with Ardiono

I connect the MATLAB with the Arduino. The problem is when I want to send a command from the Matlab to the Arduino; it requires opening contact with the Arduino. The process of opening contact with Arduino requires about three seconds. Why does the open connection process require this long time?
is there a solution?

The below code opens the connection from the Matlab to the Arduino.

a = arduino('com8', 'Uno');

Disable the auto-reset on the Arduino, or keep the serial connection open.
