qat_analyse_lim_rule_dynamic_2d: Perform a dynamic lim-rule-check

Description

This check tests data on whether it exceeds a dynamic threshold.

Usage

qat_analyse_lim_rule_dynamic_2d(measurement_vector, min_vector = NULL, 
max_vector = NULL, min_vector_name = NULL, max_vector_name = NULL, 
min_vector_identifier = NULL, max_vector_identifier = NULL)

Arguments

measurement_vector

The measurement vector (2d array), which should be tested

min_vector

A 2d array which consists of the minimum threshold values, with the same dimensions like the measurement vector

max_vector

A 2d array which consists of the maximum threshold values, with the same dimensions like the measurement vector

min_vector_name

A name or title of the minimum vector, which will be given back in the result

max_vector_name

A name or title of the maximum vector, which will be given back in the result

max_vector_identifier

The identifier of the maximum vector

min_vector_identifier

The identifier of the minimum vector

Value

It returns a list with the following entries:

Warning

There is no checking, if the maximum-vector is greater than the minimum-vector.

Details

This tests tests every element, on whether it exceeds the minimum or maximum threshold. The result will be given back as a list, which contains the result of the test as a flagvector (2d array) and its parameters. For every element of the measurement vector the flagvector contains a -1, if its exceeding its dedicated minimum vector element, a 1, if its exceeding its dedicated maximum vector element, or a 0, when no exceeding has happend. NaN-values in the measurement vector will be given back as a 0 in the flagvector, NaN-values in the minimum or maximum-vector are considered as not existing. There is no checking, if the maximum-vector is greater than the minimum-vector.
