Using Macros II
As we’ve seen, function macros are macros that return values. They correspond to Excel’s family of worksheet functions, and provide a way for you to add capability transparently to the user. In the previous session, we looked at function macros that return a single value — scalar function macros. In this session, we’ll examine array function macros — macros that return a rectangular array of values. Convolution is an example of such a macro.
To deal with array macros, we’ll have to learn about iteration and dynamic arrays — two techniques that are fundamental to manipulating arrays of data.
Array macros give you a means of handling blocks of data with a single macro, which, when combined with the array manipulation techniques we used early in the course, can dramatically simplify your spreadsheet models.

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.
