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)
