    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。 a^_W}gzzd  
    >v f-,B  
    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: Hp5.F>-  
    enableservice('AutomationServer', true) :4)(Qa(  
        enableservice('AutomationServer') %:j`%F;R  
    E!uQ>'iq.  
    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 =RZ PDu  
    f$vU$>+[  
    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: nW<nOKTnk_  
    1. 在FRED脚本编辑界面找到参考. 3Pp+>{2_?  
    2. 找到Matlab Automation Server Type Library AMASh*  
        3. 将名字改为MLAPP KK{_s=t%<

    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。 aX*9T8H/

    1. 创建Matlab服务器。 CIf@G>e-  
    2. 移动探测面对于前一聚焦面的位置。 FHEP/T\5  
    3. 在探测面追迹光线 ]{|lGtK %  
    4. 在探测面计算照度 4* I XBi7%  
    5. 使用PutWorkspaceData发送照度数据到Matlab sbhzER  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 KW3<5+w]c  
    7. 用Matlab画出照度数据 G/#m. =t  
    8. 在Matlab计算照度平均值 An^)K
