【摘要】 详细分析了 Matlab库函数的类型及其实现方式 ,指出他们执行速度快的原因在于他们是用 C语言编程 ,或者直接调用用 C语言编制的内置函数来实现的。因此 ,尽可能地调用系统提供的库函数 ,是提高用户自编 Matlab程序效率的有效途径。文中还特别就如何实现对矩阵内数据的操作给出了一些编程实例。更多还原

【Abstract】 In this paper, the reason that functions in Matlab library have high executive efficient is analyzed in detail. It is pointed out that three types of functions exist in Matlab library and they are either coded in C programming language, or directly call C functions. So calling library functions as could as possible is one of the key measures to improve the efficiency of user defined Matlab programs. Some programming examples are also given.更多还原
