Matlab是一个很好的大型数值计算软件。解释型的程序执行、即时的调试窗口、高效的矩阵运算、丰富的工具箱,使它成为了数值计算和科研工作的必备软件。虽然Matlab具有众多的优势,可是它的程序却很难完全摆脱Matlab环境运行,在界面功能上也效率低下,这些缺点我们在使用Matlab的同时,不免担忧自己的成果不能方便地对外发布。对Matlab的运行方式进行了分析,之后提出了Matlab和VC高级语言之间混合编程的方法,以及Matlab程序独立打包和如何提高Matlab程序的界面运行效率的方法。 更多还原 (Matlab is a nice large numerical software. Explain the type of program execution, real-time debug window and efficient matrix operations, rich toolbox, making it the numerical calculations and research work necessary software. Although Matlab has many advantages, but it is difficult to completely get rid of the program running Matlab environment, the interface functions inefficient, these shortcomings in the use of Matlab while we can not help but worry about their results can not easily be released. For Matlab operation mode are analyzed, and then propose a hybrid programming approach between Matlab and VC-level language, and Matlab program independent packaged and how to improve the operational efficiency of the Matlab interface procedures.
