Module source_localization 

Source localization from arrival times.

This module solves for an event position from sensors at known Cartesian coordinates. Inputs are sans-I/O: callers supply sensor positions, arrival times, and a propagation speed. Coordinates are metres in a caller-chosen 2D or 3D Cartesian frame, times are seconds, and speeds are metres per second.

Structs

Sensor
