Re: Delete all the memory except 1 matrix


what is with

SetAttributes[ClearExcept, HoldAll]
ClearExcept[context_String, keepvarList_] :=
   Saved`saved = keepvarList;
   MapThread[Set, {keepvarList, Saved`saved}]


a = 1; b = 3; c = 5; e = 7;

ClearExcept["Global`*", {a, c}]

will remove all symbols except a and c
