Matlab外部程序接口应用研究

Study on Application of Matlab External Program Interface

Matlab提供外部程序接口,便于其他开发语言使用其计算功能.描述了Matlab外部程序接口的结构,重点论述了在无Matlab环境下使用Matlab计算功能的方法———利用Matlab外部程序接口创建通用的动态链接库.参数传递出错是开发语言调用动态链接库时经常遇到的问题,提出利用中间文件传递参数的方法,成功解决这一问题.以矩阵求秩为例,详细说明了Matlab外部程序接口的使用.最后,对Matlab外部程序接口进行了评论.

In order to utilize its calculation function, Matlab provides other programming language with external program interface. The paper describes the structure of Matlab external program interface, and mainly discusses the method using Matlab calculation function, establishing dynamic link library using Matlab external program interface. Development language often encounters parameter transfer error during calling dynamic link library. Applying assistant files successfully solves this problem. The paper illustrates the use of Matlab external program interface with the example of seeking matrix＇s order. Finally, comment is made upon Matlab external program interface.
