    - #### HEAD

          public static final MathArrays.Position HEAD

      Designates the beginning of the array (near index 0).

    - #### TAIL

          public static final MathArrays.Position TAIL

      Designates the end of the array.

  - ### Method Detail

    - #### values

          public static MathArrays.Position[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (MathArrays.Position c : MathArrays.Position.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static MathArrays.Position valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null
