    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。 c6uKK h>  
    /SKr.S61e  
    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: A{J1 n  
    enableservice('AutomationServer', true) 0C p}  
    enableservice('AutomationServer') (XwLKkw0n  
    7gMtnwT  
    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 <D dHP

    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: OT& E)eR  
    1. 在FRED脚本编辑界面找到参考. G}-.xj]  
    2. 找到Matlab Automation Server Type Library #rpqt{m l  
    3. 将名字改为MLAPP 9v F2aLPk  
    Ntn md  
    QBw ZfX  
    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。 Riw7<j

    现在将脚本代码公布如下,此脚本执行如下几个步骤: +.lWck  
    1. 创建Matlab服务器。 4 ufLP DH  
    2. 移动探测面对于前一聚焦面的位置。 9sCk\`n  
    3. 在探测面追迹光线 y9L#@   
    4. 在探测面计算照度 uT/B}`md  
    5. 使用PutWorkspaceData发送照度数据到Matlab D;I`k L  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 G; [A Q:Iy  
    7. 用Matlab画出照度数据 .lBY"W&{  
    8. 在Matlab计算照度平均值 M',D  
    9. 返回数据到FRED中 bQy%$7UmX,
