    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。 k^3>Y%^1  
    [L3=x;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: 'nzg6^I7g  
    enableservice('AutomationServer', true) I5k$H$  
    enableservice('AutomationServer') t6bV?nc  
    y`Wty@  
    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 ?ZV/U!y

    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: MK%9:wZ  
    1. 在FRED脚本编辑界面找到参考. RuL i,'u  
    2. 找到Matlab Automation Server Type Library R/~p>apg8  
    3. 将名字改为MLAPP e>} s;H,  
    faE t6  
    (yH'{6g\  
    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。 Q- cFtu-w

    3. 在探测面追迹光线 ]FJjgu<  
    4. 在探测面计算照度 H*d9l2,KZS  
    5. 使用PutWorkspaceData发送照度数据到Matlab jZu[n)u'C  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 m( r,Acy6  
    7. 用Matlab画出照度数据 -$pzl,^ h  
    8. 在Matlab计算照度平均值 HZ aV7dOZ8
