`Calculates a route matrix ` given the following required parameters: ``DeparturePositions`` and ``DestinationPositions`` . ``CalculateRouteMatrix`` calculates routes and returns the travel time and travel distance from each departure position to each destination position in the request. For example, given departure positions A and B, and destination positions X and Y, ``CalculateRouteMatrix`` will return time and distance for routes from A to X, A to Y, B to X, and B to Y (in that order). The number of results returned (and routes calculated) will be the number of ``DeparturePositions`` times the number of ``DestinationPositions`` .
