    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。 lgAoJ[  
    h f)?1z4  
    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: yF:1( 4  
    enableservice('AutomationServer', true) T~?Ff|qFC  
    enableservice('AutomationServer') P{`C^W$J^  
    ]]![EHi(\  
    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 g'f@H-KCD  
    @u+]aI!`-  
    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: fb7;|LF  
    1. 在FRED脚本编辑界面找到参考. ;}WeTA_-[  
    2. 找到Matlab Automation Server Type Library GAzU?a{S  
    3. 将名字改为MLAPP ^0 )g/`H^>

    %`r$g[<G  
    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。 %Xd[(Q)

    3. 在探测面追迹光线 2W(s(-hD  
    4. 在探测面计算照度 3NqB <J  
    5. 使用PutWorkspaceData发送照度数据到Matlab yzn%<H~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w "F 9l  
    7. 用Matlab画出照度数据 5I;&mW`1,`
