Why am I getting "Internal error: The initialization of the server code is incorrect" while trying to connect Arduino Mega2560 with MATLAB?

This issue might occur if the hardware is not getting reset correctly because of the smaller delay time.
The issue can be resolved by changing the "delayValue" to 10 in "getResetDelayHook()" in "arduino.m". The file can be found by executing the following code snippet in the MATLAB Command Window:
which -all arduino
The code for the method getResetDelayHook() in "arduino.m" looks like the following:
function delayValue = getResetDelayHook(obj)
% workaround for Arduino Mega on Linux taking longer time to reset, explained in g1638539
if ispc || ismac
delayValue = 2;
delayValue = 10;
%The reset on the DTR line is via Serial only
delayValue = 0;
Change the value of delayValue inside the if statement (if ispc ismac) to 10. This will give the board more time to get reset and after that connection can be established.
