4. Include with Include

The x-y data is copied from the classic by Milo Gibaldi and Donald Perrier:

The Plot: To select x-y data pairs with Include’s argument.

The Include’s argument is not optional for Include and Match arguments equipped functions. In this example, the last 5 x-y data pairs are included (selected). Note that there is no post-computation ‘For Your Information . . .’ message for included x-y data pairs.

Note that the flag value(s) can be a number or text. A text value can have multiple characters. And a number is treated as text.

Note: Function STD.HALFLIFE.INCL returns the first-order decline half-life of the curve.

For Your Information: The Include and Match equipped functions also have the Exclude and Match version. For STD.HALFLIFE.INCL it is STD.HALFLIFE.
