Matlab产生独立可运行C代码
来源:互联网 发布:三国杀菜刀的淘宝 编辑:程序博客网 时间:2024/05/16 00:27
关于Matlab R2009a里,提到的比较多就是Real-time Workshop (虽然以前也有很多这方面的帮助)
最近跟Mathworks工程是will聊天,彻底询问了一下关于Matlab转换成独立可编译C代码的问题,得到的答复仍然是:
1:Simulink模型转换成real-time C代码已经很完美(包含比较新的Stateflow等)
2:Matlab的代码,如果是基本的代码的话,可以转换成独立运行的C代码,但是很多工具箱还不支持。
如果需要把比如说image processing, neural network等,需要用Matlab提供的基本函数改写这些代码(似乎很麻烦,所以尽量开发的时候使用Simulink)。
现在大家关心的问题是,那些函数可以直接转化成C代码,以下是函数列表:
大家可以看到,除了基本函数意外,对信号处理的函数支持的特别全面。
这也很明显,因为很多都是embedded system,信号处理是最常用的功能。
一般的算法,可以通过基本语句完成。

Works for all input values when complete numerictype information of the fi object is provided.
Works only for constant input values (value of input must be known at compile time) when complete numerictype information of the fi object is not specified.
numerictype object information must be available for non-fixed-point Simulink inputs.
