    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。 |>27'#JC  
    !zux z  
    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: * 1T&  
    enableservice('AutomationServer', true) BS /G("oZ[  
    enableservice('AutomationServer') ;6gDV`Twy  
    z3`-plE  
    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 vh"R'o

    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: +~'865{  
    1. 在FRED脚本编辑界面找到参考. cmBB[pk\  
    2. 找到Matlab Automation Server Type Library wi hH?~]  
    3. 将名字改为MLAPP ~Cl){8o

    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。 Cnnh7`

    1. 创建Matlab服务器。 ^w(p8G_-w  
    2. 移动探测面对于前一聚焦面的位置。 ?bPRxR  
    3. 在探测面追迹光线 $>*3/H  
    4. 在探测面计算照度 (>F%UY  
    5. 使用PutWorkspaceData发送照度数据到Matlab f _[<L  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >QA uEM  
    7. 用Matlab画出照度数据 Ol1e/Wv  
    8. 在Matlab计算照度平均值 7P" | J\  
    9. 返回数据到FRED中 MA;1 ;uI,
