Array
The following Formulator functions are used to work with arrays.
AT Formulator function
Extracts and returns a single value from a column (vector).
Usage
AT(
Value
,
POS
)
Value
The name of any column (vector) in the Data Series list or any operand
POS
The row number of column
Value
where the single value is located
Example
IDSAT = AT(DRAINI, 36)

None
DIFF Formulator function
For all of the values in two selected columns (vectors), returns a third column (vector) that contains the difference
coefficients.
Usage
DIFF(
V1
,
V2
)
V1
The name of any column (vector) listed under
Columns
V2
The name of any column (vector) listed under
Columns
Details
Each coefficient is calculated as follows:
V1
/
V2
Where:
•
V1
= The difference between a pair of adjacent values in the first column.
•
V2
= The difference between the corresponding values in the second column.
That is, for columns
V1
and
V2
,
DIFF
returns the following:
(V1
2
- V1
1
)/(V2
2
- V2
1
)
,
(V1
3
- V1
2
)/(V2
3
- V2
2
)
, and so on.
You can use this function to do calculations in real time (while a test is executing).
Example
GM = DIFF(DRAINI, GATEV)
