Array-Specific Builtins

Three Builtin functions have been added to the software to aid you in your use of Arrays. They are ARRAYMEAN, ARRAYSTDDEV, and ARRAYSUM. The basic definition of these builtins is summarized here. See the Array Functions section of Chapter 7 for details on how to use them.

 
ARRAYMEAN(<arrayed variable>)

The ARRAYMEAN Builtin calculates the arithmetic mean of the elements in a one or two-dimensional Array. The calculation is defined as the sum of the elements, divided by the number of elements in the Array. The calculation can be done in either an arrayed or a non-arrayed converter or flow.

 
ARRAYSTDDEV(<arrayed variable>]

The ARRAYSTDDEV Builtin calculates standard deviation for all the elements in a given arrayed variable. The calculation can be done either in an arrayed or a non-arrayed variable.

 
ARRAYSUM(<arrayed variable>]

The ARRAYSUM Builtin calculates the sum of all the elements in a given one or two-dimensional Array. The calculation can be done in either an arrayed or a non-arrayed variable.
