功率谱分析是信号处理的重要内容，包括频率解与动态区域解、误差改进方法等程序(Power spectrum analysis is an important aspect of signal processing, including the frequency of solutions and dynamic regional solutions to improve the methods of procedure error)

VC＋＋与MATLAB的混合编程 ：This paper is origined from the API(Application Programme Interface)between Matlab6p5 and Visual C++6．0．and has mainly discussed on the idea about how to make a mixed programme with language C++ and Madab，what’s inore，has illustrated the scheme and difficulties to enhance the speed and efficien— cy of the simulation software and code executing．Consequently，it provides the students and engineers with an effective reference． (：This paper is origined from the API(Application Programme Interface)between Matlab6p5 and Visual C++6．0．and has mainly discussed on the idea about how to make a mixed programme with language C++ and Madab，what’s inore，has illustrated the scheme and difficulties to enhance the speed and efficien— cy of the simulation software and code executing．Consequently，it provides the students and engineers with an effective reference． )
