I have a tricky question. I used R2009a on my mac before. I can just type "matlab" (without specifying the full path or cd to that folder) and matlab just pop out. Moreover, I can type "nohup matlab <xxx.m> xxx.out &" to run multiple m-file at the same time. However, once I upgraded to R2013a, it doesn't work. Does anyone know why? Thank you so much!
