Notational Conventions - mfx - 3.1

The following notational conventions are observed in this manual:   

• Braces ( { } ) indicate that a choice must be made among the alternatives listed.
• Brackets ( [ ] ) indicate an optional item. Two or more items in brackets are mutually exclusive options; only one can be chosen for a particular application.
• Defaults are underlined.
• Upper-case letters and numbers, commas, equal signs, and parentheses must be entered exactly as indicated. Lower-case letters represent variables, which must be replaced by actual values.
• Subscripts show position in a series, and three dots indicate an ellipsis.   

For example, a₁,a₂,...,a₅ is equivalent to a₁,a₂,a₃,a₄,a₅ and represents five “a” items (variables which will be replaced with actual values). Examples, which may be entered exactly as shown, are presented in typeface as follows:
