The code implements the elliptic model for social fluxes as presented in

The elliptic model for communication fluxes, Herrera-Yagüe et al

General syntax

Fluxes = elliptic_model(lat, lng, pop, FLEX=0, option="ellipse", totalSum=1)

• lat is a 1-D vector containing latitudes of locations
• lng is a 1-D vector containing longitudes of locations
• pop is a 1-D vector containing the population of each location
• FLEX is the flexibility parameter in kilometers. Defaults to 0
• options either "ellipse" or "union" depending on the model to be applied
• totalSum desired sum of all ellemnts in the resulting Fluxes matrix. Defaults to 1.
