Laser communications offer a powerful alternative at a time when space is becoming crowded and radio frequencies increasingly scarce. Because laser beams spread far less than radio waves, they provide more secure links and can carry much more information.
Another way to approach the linear combination is to look at it geometrically. This is where the idea of barycentric coordinates can help. A barycentric coordinate system describes the location of a point as the weighted sum of the regular coordinates of the vertices forming a simplex. In other words, it describes a linear combination with respect to a set of points, where in -dimensional space.，推荐阅读搜狗输入法下载获取更多信息
