Vector Builtins

b255 - The parser now recognises 6 more mathematical functions from the third party Frontiermath dll. Called, Vector builtins , they operate only on multiple valued arithmetic variables and return a double value computed on the values of one instance of a variable. These are :

• max
• min
• mean
• popSD
• stdDeviation
• sum

For example, sum(X) where x is a message variable, returns the sum of all the values of X in one message; mean(x) their arithmetic mean and so on.

The tailored scripts which compute these values are able to intelligently cache values in the interests of reducing overhead. To make use of Vector builtins you must have your server administrator download and install the dll from the FrontierMath web page (see <http://www.es-designs.com/downloads/frontiermath.html>). Many thanks to to Arnold Lesikar, Andre Radke and Tom Clifton who graciously made the dll available in Frontier.

b261 -- two Boolean vector builtins have been implemented vectorAnd and vectorOr. They return the composite and (or) of all the values of the multiple valued boolean variable passed as parameter.

• vectorAnd
• vectorOr

b273 . two new vector builtins ( see b255 release note) for timestamp multiple values variables were implemented. Earliest return the first timestamp from the vector if it is ordered by time, Earliest the last.
