Constants - declaration of constants

Constants[c1, c2, ..., ci, ..., cn]
allows one to declare constants
  • c1, c2, ..., ci, ..., cn - constants identifiers.
  • In the Atlas package any identifier is treated as 0-form i.e. as non-constant scalar (if it not declared as constant, p-form, tensor etc. (see Types)).
  • In the Atlas package constants are constant 0-forms.
  • Some constants are predefined such as Catalan, Pi, I and _Z (for RootOf procedure)
  • The constant identifier can be either symbolic or indexed.
