摘　　要：在高铁CPⅢ控制网平差中要进行大量的矩阵运算,MATLAB是强大的矩阵运算工具,VB.NET是一个高效快速的软件开发平台。VB.NET调用MATLAB编译的动态连接库进行矩阵运算,减少了代码的编写和复杂算法的研究,提高了平差程序的运算效率。In the adjustment of CP Ⅲ high-speed railway control network, large matrix calculation is needed. MATLAB is a powerful matrix calculation tool, and VB. NET is a rapid and efficient software development platform. When taking matrix operation, the dynamic link library compiled by MATLAB is called by VB. NET platform, which greatly reduces the amount of coding work and the depth of complex algorithm. Experiments show that the efficiency of the adjustment program is improved significantly.
