Application of MATLAB and C++ Builder based on COM to surveying program development

With MATLAB COM builder in MATLAB 6.5 as a conversion tool, Matlab's M-function can be converted into a COM component applied in C++ Builder 6.0. The integrated software can not only take full advantages of C++ Builder and MATLAB, but also run independently without MATLAB. The paper gives a sample program DUPQJSV in surveying adjustment,and it also studies the release of MATLAB application module on the Web.
