disp(distance_to_surface); ``` 上述示例中,我们首先计算地球的平均半径R,然后使用distance函数计算两个相同经纬度的点之间的地表距离,然后将该距离减去地球的半径R,即可得到该点到地球表面的距离。 3. geodetic2ecef:该函数可将地理坐标转换为ECEF(Earth-Centered, Earth-Fixed)坐标系。可以通过给定其中一点的经纬...

Besides, with the same two points, I tried using the lla2ecef, and ecef2enu, the outputs were different from the the geodetic2enu method. Thanks very much! 1 件のコメント David Young2015 年 2 月 4 日 Presumably the LengthUnit property of referenceEllipsoid is metres? (I can't check...
