MATLAB软件是以矩阵为单位进行数据的运算与处理，MATLAB的程序设计过程中，对象的句柄是非常重要的一个概念。每个对象都有自己独立的句柄，通过操作句柄，来实现对象的控制和修改。 GPS测量的成果是基于WGS84椭球的纬、经度坐标和大地高，而我们实际应用中需要用到的是北京54或西安80的高斯投影平面坐标或者是地方坐标，因此就存在一个坐标转换的问题。本文介绍两种坐标转换方法：空间三维七参数坐标转换方法和平面二维四参数转换方法，利用这两种方法通过MATLAB设计界面并编写程序实现对Excel中的坐标数据进行坐标转换。

MATLAB software based on the matrix as a unit for data and processing operations, In the MATLAB program design process , object handle is a very important concept . Each object has its own separate handler,by operating the handle, to achieve the object of the control and modify . GPS survey results are based on WGS84 ellipsoid latitude, longitude coordinates and geodetic height, And we need to use the actual application is Beijing Geodetic Coordinate System 1954 or Xi'an Geodetic Coordinate System 1980 Plane Coordinate or local coordinates, Therefore, there exists a coordinate transformation problem. This article describes two coordinate conversion method: Three-dimensional coordinate space conversion seven-parameters method and Two-dimensional four-parameter conversion method,Through the use of these two methods MATLAB interface design and programming to achieve the coordinate data in Excellcoordinate conversion.
