qat_analyse_roc_rule_static_1d: Perform a static roc-rule-check

In qat: Quality Assurance Toolkit

Description

This check tests data on whether the change between two consecutive data points exceeds a static threshold.

Usage

qat_analyse_roc_rule_static_1d(measurement_vector, max_upward_value, 
max_downward_value)

Arguments

measurement_vector	The measurement vector, which should be tested
max_upward_value	The upward threshold
max_downward_value	The downward threshold, which should be positive definite

Details

This check tests two consecutive elements, on wether the change of values between those two exceeds the upward or downward threshold. The result will be given back as a list, which contains the result of the test as a flagvector and its parameters. For every change between two elements of the measurement vector the flagvector contains a -1, if its exceeding the downward value, a 1, if its exceeding the upward value, or a 0, when no exceeding has happend.

Value

It returns a list with the following entries:

flagvector	A vector of length of measurement vector. For every change between two elements of the measurement vector the flagvector contains a -1, if its exceeding the downward value, a 1, if its exceeding the upward value, or a 0, when no exceeding has happend.
max_upward_value	Give back the given max\_upward\_value
max_downward_value	Give back the given max\_downward\_value
