Which statement about Matrix to Calculation Procedure linking is correct?

• A. Adding a Matrix Lookup Calculation Step to the Calculation Procedure
• B. Dragging the Matrix Name from the Matrices palette
• C. Entering the Matrix Name in the Calculation Procedure's Matrix attribute
• D. None of the above

Answer: (A)

The key idea is that a Matrix is brought into a Calculation Procedure by using a Matrix Lookup Calculation Step. This dedicated step is designed to read values from a Matrix and perform the defined mappings, producing outputs that can be used later in the procedure. You don’t link by dragging the Matrix name or by setting a top-level Matrix attribute on the Procedure; instead, you configure the Matrix Lookup step to reference the specific Matrix, and that step handles the lookup logic and passes the results along. This makes the Matrix available to the Calculation Procedure precisely where needed.
