Example 2: Multiply an array by a constant 14/8
Session Links
  • The macro takes two arguments:
    • Array of any size
    • Constant
  • It returns an array equal to array * constant
  • Plan of calculation:
    • Create an array to hold the answer
    • Iterate through the argument array:
      • Pick up the array element
      • Multiply it by the constant
      • Insert the result into the corresponding place in the answer array
  • This one is trickier because we don’t know the size of the array
  • This is really useless, because Excel can do this without a macro

In our next example, we multiply an array by a constant, which Excel already can do. In our previous example, we knew that the arrays were 3x3. The twist here is that we won’t assume, as we write the code, that we know how big the array is.

This will require us to compute the size of the answer array and declare it “on the fly.”

How to Measure the Value of a Function Macro

The value of a function macro increases with frequency of use, the complexity of the calculation it performs, and the area of the result it returns. As you examine the computations you perform routinely in your work, make note of those computations that meet these criteria. Before committing yourself to writing a macro to carry out one those computations, try various methods for implementing it using standard built-in worksheet functions. That effort might clarify for you the kernel of the computation that benefits most from a macro-based approach.
