    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。 }=Ul8 <  
    .y<u+)  
    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: KwU;+=_.  
    enableservice('AutomationServer', true) &x7iEbRs  
    enableservice('AutomationServer') zd/kr  
    R3%%;`c=  
    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 8OiCldw:HN

    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: fbD,\ rjT  
    1. 在FRED脚本编辑界面找到参考. <w`EU[y_  
    2. 找到Matlab Automation Server Type Library {@6:kkd  
    3. 将名字改为MLAPP voQJ!h1  
    D -d  
    Tl2(%qB  
    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。 <Zvvx

    3. 在探测面追迹光线 `][vaLd`Q  
    4. 在探测面计算照度 ;wkMa;%`g|  
    5. 使用PutWorkspaceData发送照度数据到Matlab H]7bqr  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 YgdQC(ib  
    7. 用Matlab画出照度数据 ]6M,s0  
    8. 在Matlab计算照度平均值 c g)> A  
    9. 返回数据到FRED中 ==Xy'n9'
