    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。 [zx|eG<&-  
    ll2Vk*xs  
    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: kC31$jMC3!  
    enableservice('AutomationServer', true) A _i zSzC1  
        enableservice('AutomationServer') 0e\y~#-  
    KC]tY9 FK  
    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  Oq}ip  
    o?y"]RCM  
    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: "/!'9na{QL  
    1. 在FRED脚本编辑界面找到参考. \ j:AR4  
    2. 找到Matlab Automation Server Type Library 506V0]`/  
        3. 将名字改为MLAPP l1DI*0@

    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。 BCBUb

    2. 移动探测面对于前一聚焦面的位置。 Az9J\V~"  
    3. 在探测面追迹光线 NA\x<  
    4. 在探测面计算照度 NZfd_? 3  
    5. 使用PutWorkspaceData发送照度数据到Matlab s&0*'^'O[S  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 0R*}QXph  
    7. 用Matlab画出照度数据 :v#8O~
