    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。 OYJy;u3"  
    9x,Aqr$t  
    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: w0Fi~:b  
    enableservice('AutomationServer', true) 6u3DxFiTm  
    enableservice('AutomationServer') 5#.uA_Fov  
    N 5rY*S  
    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 _F^k>Lq&d  
    Ru Q\H0pr  
    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: 0Ng6Xg(QHc  
    1. 在FRED脚本编辑界面找到参考. ~F*pV*  
    2. 找到Matlab Automation Server Type Library f- pt8  
    3. 将名字改为MLAPP 0K'lr;  
    :4h4vp<  
    GA{>=Q _~  
    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。 v#.FK:u}

    现在将脚本代码公布如下,此脚本执行如下几个步骤: >U^AIaW  
    1. 创建Matlab服务器。 {nT !|S)$  
    2. 移动探测面对于前一聚焦面的位置。 v@;:aN  
    3. 在探测面追迹光线 <pGPuw|~I  
    4. 在探测面计算照度 -9/YS  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0/<}.Z]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 !o*BRR*  
    7. 用Matlab画出照度数据 GEwgwenv  
    8. 在Matlab计算照度平均值 4x=rew>Ew  
    9. 返回数据到FRED中 y-}lz#N
