ENVIExamples::SetExampleData

Use the SetExampleData method to manually set attribute names, examples, and class values for an ENVIExamples object.

Syntax

ENVIExamples.SetExampleData, Examples [, Keywords =value]

Arguments

Examples (required)

Specify an array of size n x m, where n is the number of examples and m is the number of features.

Keywords

ATTRIBUTE_NAMES (optional)

Set this keyword to a string array of attribute names.

ERROR (optional)

Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See Manage Errors for more information on error handling in ENVI programming.

CLASS_VALUES (optional)

Set this keyword to an integer array of class values, which are numbers assigned to each unique class. The array must have the same number of elements as the Examples array.
