More examples of multicell array formulas
The previous chapter provided an introduction to arrays and array formulas, and also presented
some basic examples to whet your appetite. This chapter continues the saga and provides many
useful examples that further demonstrate the power of this feature.
I selected the examples in this chapter to provide a good assortment of the various uses for array
formulas. Most can be used as-is. You will, of course, need to adjust the range names or
references that you use. Also, you can modify many of the examples easily to work in a slightly
different manner.
Working with Single-Cell Array Formulas
As I describe in the preceding chapter, you enter single-cell array formulas into a single cell (not
into a range of cells). These array formulas work with arrays contained in a range or that exist in
memory. This section provides some additional examples of such array formulas.
The examples in this section are available on the companion CD-ROM. The file is named
single-cell array formulas.xlsx .
Summing a range that contains errors
You may have discovered that the SUM function doesn’t work if you attempt to sum a range that
contains one or more error values (such as #DIV/0! or #N/A). Figure 15-1 shows an example. The
formula in cell C11 returns an error value because the range that it sums (C4:C10) contains errors.
