    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。 Zmx[u_NG  
    *7 L*:g  
    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: !A R$JUnX  
    enableservice('AutomationServer', true) JGmW>mH  
    enableservice('AutomationServer') R<r"jOd]  
    [w iI  
    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 b0\'JZ  
    ONx|c'0g  
    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: ZqI.n4:9  
    1. 在FRED脚本编辑界面找到参考. D+ki2UVt&  
    2. 找到Matlab Automation Server Type Library Y~RZf /`  
    3. 将名字改为MLAPP HSt|Ua.c/h

    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。 %}z/_QZ

    3. 在探测面追迹光线 )g4oUZDF  
    4. 在探测面计算照度 TO\%F}m(  
    5. 使用PutWorkspaceData发送照度数据到Matlab a S- rng  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 (wJtEoB9^  
    7. 用Matlab画出照度数据 <`dF~   
    8. 在Matlab计算照度平均值 "Y&+J@]  
    9. 返回数据到FRED中 h6*=Fn7C
