Compute a travel time/distance matrix between origins (rows) and destinations (columns). Costing "auto", "truck" (with optional `truck` profile as in `route`), "bicycle", "pedestrian" or "motor_scooter". Returns durations_s[i][j] in seconds and distances_m[i][j] in metres; null cells are unreachable pairs. Up to 10,000 cells per call (origins × destinations). Optional `exclude_polygons` for before/after scenarios ("close this bridge and recompute the matrix"): an array of polygons, each an array of [lon, lat] pairs forming one ring — longitude FIRST — whose intersecting roads are excluded from every cell's path finding. Applies to the Valhalla engine; unsupported on the GraphHopper engine, where it is ignored.
