5. Include and Match Option

5. Include and Match Option

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

The Plot: [1] Not to include (select) the non-numeric x-y data pair. [2] To augment the Include’s array with Match? value.

Using Include’s array alone would generate an alert message (and the computation aborts):

The Match? value serves to refine the inclusion. Only if a case-sensitive match is found between the Match value and flag’s values(s) will the corresponding x-y data pair be included. Note that there is no post-computation ‘For Your Information . . .’ message for the 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. In this example, there are two flags populated with more than one values.

In this example the Match? value references a cell value. The Match value can also be directly entered into the Match? value argument.

To find out more about alert messages see Alert Messages in user guide.

Note: Function STD.LAMDA.INCL returns the first-order decline rate constant of the curve.

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