qat_analyse_noc_rule_2d: Perform a noc-rule-check

In qat: Quality Assurance Toolkit

Description

This check tests data on whether it changes after a given amount of values.

Usage

qat_analyse_noc_rule_2d(measurement_vector, max_return_elements)

Arguments

measurement_vector	The measurement vector (2d array), which should be tested
max_return_elements	Number of coherent elements, which are allowed to have no change between the single values, without indicate an error

Details

This check tests the given measurement vector (2d array) in direction of the first dimension, on how much values in a row gut the same value. If the number of values, which is defined by max\_return\_elements prior to the actual element got the same value as the actual element, the resulting flagvector will be set to 1 on the actual position. Else it will be set to 0.

Value

It returns a list with the following entries:

flagvector	flagvektor (2d array) with the dimension of measurement vector, where a 0 indicates no error and a 1 that there is a repetition error
max_return_elements	Give back the given max\_return\_elements
