    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。 k[f2`o=  
    ;"M6}5dQ4  
    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: 8H7#[?F  
    enableservice('AutomationServer', true) ]Thke 4  
    enableservice('AutomationServer') ny KfM5s_  
    +jhzE%  
    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 n.g-%4\q  
    t?"(Zb  
    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: @&?(XY 'M%  
    1. 在FRED脚本编辑界面找到参考. bTJ<8q  
    2. 找到Matlab Automation Server Type Library (_ G>dP_  
    3. 将名字改为MLAPP .57p4{  
    f#z:ILG=  
    yksnsHs}d  
    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。 RJD{l+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ,IB\1#  
    1. 创建Matlab服务器。 /Bt!xSI  
    2. 移动探测面对于前一聚焦面的位置。 ~u&gU1}  
    3. 在探测面追迹光线 e|oMbTZ5m  
    4. 在探测面计算照度  .2&L.  
    5. 使用PutWorkspaceData发送照度数据到Matlab XP)^81i|  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8&U Mmbgy  
    7. 用Matlab画出照度数据 ?z>J7 }w*=  
    8. 在Matlab计算照度平均值 lJ;Wi  
    9. 返回数据到FRED中 sJZ2e6?n
