some partners asked me how we determine the number of "transactions" for distance matrix calculations because they were surprised about the volumes in their reports. Here's a little description. So if you want to change from a
(m_old x n_old) shape to a (m_new x n_new) shape the delta is (m_new – m_old) x n_new + (m_old) x (n_new - n_old)
To simplify this for suare shaped dima's:
from (old)² to (new)² it is delta=(new²)-(old²)

Best regards,
