    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。 f\:I1y  
    %7Gq#rq  
    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: Xi=4S[.4  
    enableservice('AutomationServer', true) y}W*P#BDO  
        enableservice('AutomationServer') I wu^@  
    4LJOT_  
    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 nxuR^6 Ai  
    :yOJL [x  
    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: &';@CeK  
    1. 在FRED脚本编辑界面找到参考. "?J f#  
    2. 找到Matlab Automation Server Type Library (<|1/^~=  
        3. 将名字改为MLAPP PJh97%7

         D6P/39}W  
    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。 oTpoh]|[

    3. 在探测面追迹光线 =?hbi]  
    4. 在探测面计算照度 tkdyR1-  
    5. 使用PutWorkspaceData发送照度数据到Matlab YgkQF0+  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 G;AV~1i:~  
    7. 用Matlab画出照度数据 >>>MTV f  
    8. 在Matlab计算照度平均值 / DS T|2  
    9. 返回数据到FRED中 c{/KkmI
