    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 $4CsiZ6  
    / Kj;%  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: `C*psS  
    enableservice('AutomationServer', true) f1Gyl  
    enableservice('AutomationServer') f5CnJhE|)  
    p!LaR.8]  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Y-"7R>^I

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: +227SPLd  
    1. 在FRED脚本编辑界面找到参考. &nn+X%m9g  
    2. 找到Matlab Automation Server Type Library [k,FJ5X  
    3. 将名字改为MLAPP =:^f6"p&Z  
    hQJ-  ~  
    d[e;Fj!  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 u,S}4p&l

    现在将脚本代码公布如下,此脚本执行如下几个步骤: c~Z\|Y`#B  
    1. 创建Matlab服务器。 <:0d%YB)  
    2. 移动探测面对于前一聚焦面的位置。 B}ASZYpW>  
    3. 在探测面追迹光线 hL/  
    4. 在探测面计算照度 N07FU\<9  
    5. 使用PutWorkspaceData发送照度数据到Matlab Gc:oS vm  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 m-|~tve  
    7. 用Matlab画出照度数据 n0@\x=9  
    8. 在Matlab计算照度平均值 oIY@xuj  
    9. 返回数据到FRED中 [/eRc
