Could anyone confirm this is a bug of Scilab? Is it a known bug? Scilab got stuck on my PC after I entered the command below: figure(1);plot2d("nl", [1:2], [%nan; 1]+%eps); I had to kill the process on the windows task manager. I tested it multiple times with the same result. I am using Scilab 5.4.1 on Windows 7. Iai
