Description
Block Detrend removes the linear trend from the input vector lengths by subtracting the straight line that best fits the data in the least squares sense.
The line of least squares — this is a line with parameters and which minimize the number of
for evenly distributed values , where — -th element in the input vector. Output Data, They always represent a column vector on .
