    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。 `Dj-(~x  
     1D6iJ  
    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: 5@?P 8  
    enableservice('AutomationServer', true) l2xM.vR  
        enableservice('AutomationServer') }yUZ(k#  
    `w2hJP  
    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 -FwOX~s/'  
    O0e6I&u :  
    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:  IS!sJc  
    1. 在FRED脚本编辑界面找到参考. TeQpmhN  
    2. 找到Matlab Automation Server Type Library 7Y:1ji0l  
        3. 将名字改为MLAPP @`)A )  
         |[8&5[);

    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。 8@Pv nOL

    3. 在探测面追迹光线 >IsRd  
    4. 在探测面计算照度 &0~E+ 9b  
    5. 使用PutWorkspaceData发送照度数据到Matlab Fc{hzqaP8  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Tm qtj  
    7. 用Matlab画出照度数据 _uID3N%
