Writeline function does not WORK in script problem

Hello,

I am trying to connect my device (arduino uno) and MATLAB. Although readline works well, i have problem with writeline funtion. While it well work in command line (I added another writeline command right next to it to check the problem caused by speed and it still works welll in command line), the function does not work when i used it as a script line. Do you have any suggestion (not setup connection everytime) ?

EDIT; After connection is setted if i run the function in command window for one time, then it works fine in script also. But is there anyway to run it without using command window ??

EDIT2; the problem is solved by adding one second delay right after connection seting up.
