OwnValues is the one that stores value assignments to the symbol. This code returns the list of symbol names (as strings) for those symbols whose OwnValues is non-empty, i.e. the symbol has been assigned a value: Select[Names["Global`*"], ToExpression[#, InputForm, OwnValues] =!= {} &]Mathematica handle's variables in a subtly different way to the way we handle them in ordinary written mathematics. Let's go over the details: Mathematica variables can have multiple letters in their names, and even numbers (except numbers are not allowed in the first position.) e.g. valid variable names are x, or pressure, or even sample4.May 29, 2011 at 13:16. @500, I do not know how to find if it is a function you defined, but for build in function, this is how I do it isFunction [name_String]:=Module [ {m}, If [Length [SyntaxInformation [Symbol [name]]]>0,True,False]]; for example: isFunction ["Plot"] will return True. this works only for functions which have ...May 29, 2011 at 13:16. @500, I do not know how to find if it is a function you defined, but for build in function, this is how I do it isFunction [name_String]:=Module [ {m}, If [Length [SyntaxInformation [Symbol [name]]]>0,True,False]]; for example: isFunction ["Plot"] will return True. this works only for functions which have ...
