WebI have looked at this question but it hasn't really given me any answers.. Essentially, how can I determine if a strong correlation exists or not using np.correlate?I expect the same output as I get from matlab's xcorr with the coeff option which I can understand (1 is a strong correlation at lag l and 0 is no correlation at lag l), but np.correlate produces values … http://www.duoduokou.com/python/17385425684880040874.html
