    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。 \ziF(xTvqG  
    e0 EJ[bG  
    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: OSU=O  
    enableservice('AutomationServer', true) mj~CCokF{?  
        enableservice('AutomationServer') A'2:(m@{T  
    YgDasKFm'  
    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 ,_O[; L  
    5~QB.m,>  
    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:  f;a6ux#  
    1. 在FRED脚本编辑界面找到参考. VTa8.(i6v  
    2. 找到Matlab Automation Server Type Library %Kp}Wo6  
        3. 将名字改为MLAPP 1XRVbQt  
          1qF.0  
         b L~<~gA  
    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。 } q(0uzaG

    现在将脚本代码公布如下,此脚本执行如下几个步骤: TmiQq'm[b  
    1. 创建Matlab服务器。 qZG >FC37  
    2. 移动探测面对于前一聚焦面的位置。 U>XGJQ<NS  
    3. 在探测面追迹光线 y5}|Y{5  
    4. 在探测面计算照度 gE~31:a^  
    5. 使用PutWorkspaceData发送照度数据到Matlab GS%Dn^l  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 k=[R o  
    7. 用Matlab画出照度数据 0:EiCKb)ol  
    8. 在Matlab计算照度平均值 jL<.?HE  
    9. 返回数据到FRED中 1;V5b+b
