I am a new user. According to a documentation, Clear["context`*"] clears all symbols in a particular context.

I want to clear everything (functions, variables, etc..) After I use the above command, my function n1[x,y] is still defined.

Thanks

    $\begingroup$ try CleanSlate package I do not know if it still works on V 10 or not. CleanSlate, tries to do everything possible to return the kernel to the state it was in when the CleanSlate.m package was initially loaded (I myself, when I want to make sure everything is clear, just restart the kernel) $\endgroup$

  • $\begingroup$ Beware: Dynamic content, including Manipulate and DynamicModule, in open notebooks can work against simply clearing or quitting the kernel. $\endgroup$

    $\begingroup$ Did you literally execute Clear["context`*"] or did you try Clear["Global`*"]? Or perhaps another context? $\endgroup$

  • $\begingroup$ You have to delete all outputs containing Dynamic or Initialization for DynamicModules since those are going to be evaluated after you quit kernel. $\endgroup$

This will, as it says, remove all symbols and definitions made in the global context:

Remove["Global`*"]

As Nasser points out, the command Quit[] will quit the kernel completely. It will kill the kernel process, stopping the kernel from using any memory or remembering anything at all. Evaluating any command will re-start the kernel from scratch.
