    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。 Z$Z`@&U=  
    w+Ad$4Pf"  
    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: gBMta+<fE~  
    enableservice('AutomationServer', true) [Dnusp7e  
    enableservice('AutomationServer') w#W5}i&x  
    l#b:^3  
    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 4DvdE t

    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: J=b*  
    1. 在FRED脚本编辑界面找到参考. #]"/{Z  
    2. 找到Matlab Automation Server Type Library #1MKEfv(~  
    3. 将名字改为MLAPP A3xbT\xdg

    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。 "K 8nxnq

    3. 在探测面追迹光线 JAN|aCzD  
    4. 在探测面计算照度 %?@x]B9Y8E  
    5. 使用PutWorkspaceData发送照度数据到Matlab MdLj,1_T  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 tAaYL \~  
    7. 用Matlab画出照度数据 %j%%Rn  
    8. 在Matlab计算照度平均值 `Rrr>vj
