    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。 ~o:lh],~  
    s[:e '#^  
    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: j)Z3m @Ii5  
    enableservice('AutomationServer', true) .tB[8Y=J  
        enableservice('AutomationServer') whW"cFg  
    /*Z ,i&eC  
    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 C7%+1w'D8  
    HYgq@47$[  
    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: ]R^?Pa1Te4  
    1. 在FRED脚本编辑界面找到参考. =G*rfV@__V  
    2. 找到Matlab Automation Server Type Library .K(IRWuw  
        3. 将名字改为MLAPP 4ze-N8<[  
         .M_[tl  
         B7qm;(?X&  
    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。 JLT ^0wBB

    3. 在探测面追迹光线 ugg08am!  
    4. 在探测面计算照度 dBY,&=T4p  
    5. 使用PutWorkspaceData发送照度数据到Matlab hV_eb6aj}P  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 m(nGtrQJm  
    7. 用Matlab画出照度数据 ^8dJJ*  
    8. 在Matlab计算照度平均值  \p"`!n
