    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。 g?` g+:nug  
    o#3?")>|  
    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: )OQhtxK  
    enableservice('AutomationServer', true) U<,@u,_Ja  
    enableservice('AutomationServer') M2HO!btf  
    AzAD76iNv  
    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 :K.%^ag=j  
    ?#; oqH<  
    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: Z0&^U#]  
    1. 在FRED脚本编辑界面找到参考. 88}+.-3t$  
    2. 找到Matlab Automation Server Type Library  }/~%Ysl  
    3. 将名字改为MLAPP I@Zd<Rn

    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。 _svEPHU

    1. 创建Matlab服务器。 5\93-e  
    2. 移动探测面对于前一聚焦面的位置。 @P=St\;VP  
    3. 在探测面追迹光线 /2}o:vLj  
    4. 在探测面计算照度 r /v'h@  
    5. 使用PutWorkspaceData发送照度数据到Matlab <@i.~EL  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Y g>W.wA  
    7. 用Matlab画出照度数据 z'@j9vT
