clear all clears Matlab’s memory in a brutal way. In your case Matlab warns, that some functions cannot be removed. Perhaps they are callbacks of GUIs or timers, or the currently processed M-code. In addition all persistent variables are cleared and many functions need a time-consuming re-initialization afterwards.
Why clear all is bad Matlab?
clear all clears Matlab’s memory in a brutal way. While removing all locally used variables might be useful for scripts, which are short hacks or prooves of concept, it is evil is productive code.
