Details
This check tests two consecutive elements (in the direction of the first dimension), 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.
