abstract: Building on top of the 'RcppArmadillo' linear algebra functionalities to
  do fast spatial interaction models in the context of urban analytics, geography,
  transport modelling. It uses the Newton root search algorithm to determine the optimal
  cost exponent and can run country level models with thousands of origins and destinations.
  It aims at implementing an easy approach based on matrices, that can originate from
  various routing and processing steps earlier in an workflow. Currently, the simplest
  form of production, destination and doubly constrained models are implemented. Schlosser
