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

Value

It returns a list with the following entries:

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.
