Session 14

Using Macros II
Summary of Pages


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.

Below is a summary of pages for Session 14.
