I recently upgraded my Matlab to 2019a from 2013b. Interestingly, I found that the newer version has "echo on" as default - thus, every time I run scripts, the lines in the scripts are displayed in the command window. Curretly, I am manually turning off echo by typing "echo off" in the command window after starting Matlab, but it is a bit cumbersome. I tried to find a related option in the "Pereferences" menu, but I couldn't find one. Am I missing something? Is there any better way to make "echo off" as the default mode of operation in my Matlab?
