    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。 {S<>&?XB  
    Qpt&3_   
    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: + q''y  
    enableservice('AutomationServer', true) _}mK!_`  
    enableservice('AutomationServer') 4.K'\S  
    ue8qIZH  
    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 =3 +l  
    L fl-!1  
    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: .1QgK  
    1. 在FRED脚本编辑界面找到参考. #)`A7 $/,  
    2. 找到Matlab Automation Server Type Library *]x*B@RF  
    3. 将名字改为MLAPP >?YNW   
    3,);0@I  
    Ze!92g  
    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。 8@M'[jT

    现在将脚本代码公布如下,此脚本执行如下几个步骤: On1v<SD$[  
    1. 创建Matlab服务器。 0m+8P$)C%  
    2. 移动探测面对于前一聚焦面的位置。 D6Y6^eS-  
    3. 在探测面追迹光线 cX At :m  
    4. 在探测面计算照度 GIv){[i  
    5. 使用PutWorkspaceData发送照度数据到Matlab z]Acs  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 &!y]:CC{  
    7. 用Matlab画出照度数据 ^ft]b2i  
    8. 在Matlab计算照度平均值 mYNEz @  
    9. 返回数据到FRED中 U&y`-@A4
