DeclarePackage

DeclarePackage["context`", {"name1", "name2", ...}]

  • You can use DeclarePackage to tell Mathematica automatically to load a particular package when any of the symbols defined in it are used.
Use of the symbol implies reading the corresponding package automatically:

Use of the symbol implies reading the corresponding package automatically:
