ENVIConfusionMatrix::Precision

ENVIConfusionMatrix::Precision

The Precision function method returns a precision value, which is the same as User Accuracy.

Example


See the following topics for code examples:

Syntax


Result = ENVIConfusionMatrix.Precision([, ERROR=variable])

Return Value


This function method returns a precision value from the confusion matrix.

Arguments


None

Keywords


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.
