中文说明：应用背景该程序可以运用到不知道一点的经纬度，而知道另一点的经纬度和到未知点的距离 ，就能通过该程序计算出来。已知一点的经纬度，同时测量出已知点到未知点的距离，通过MATLAB的的程序计算将计算要素带入到设计的GUI界面，通过计算就能算出未知点的经纬度。应用于建筑等需要知道点的位置的场合。关键技术通过MATLAB的的程序计算将计算要素带入到设计的GUI界面，通过计算就能算出未知点的经纬度。程序计算的公式是球体的余弦公式，主要是gui界面的设计的程序是主要编程的重点。gui界面方便，直观的优点也是该程序的亮点。
English Description：
Application backgroundThe program can be used to do not know the latitude and longitude, and know the latitude and longitude of the other point to the distance of the unknown point, can be calculated by the program. Known point of latitude and longitude, while measuring the distance to the unknown point to the unknown point, through the calculation of the MATLAB program to design the GUI interface, the calculation will be able to calculate the latitude and longitude of the unknown point. Application in building, etc., need to know the location of the location.Key TechnologyThrough the calculation of the MATLAB program to design the GUI interface, the longitude and latitude of the unknown points can be calculated by the calculation. The formula is the formula of the sphere of the cosine formula, the main GUI interface design is the main focus of programming. GUI interface is convenient, intuitive advantages of the program is also a bright spot.
