    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。 AT'_0> x8  
    mw4'z,1Q  
    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: "k_n+cH%  
    enableservice('AutomationServer', true) ixI5Xd<  
    enableservice('AutomationServer') )2<B$p  
    J*q=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 Zc' >}X[G  
    P/1UCITq}  
    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: y uK5r  
    1. 在FRED脚本编辑界面找到参考. _QOOx+%*5  
    2. 找到Matlab Automation Server Type Library {eD>E(Y@z1  
    3. 将名字改为MLAPP @y~BYiKs

    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。 A86lyBDQ*

    现在将脚本代码公布如下,此脚本执行如下几个步骤: &L~31Ayj&  
    1. 创建Matlab服务器。 'i h  
    2. 移动探测面对于前一聚焦面的位置。 >!v,`O1  
    3. 在探测面追迹光线 @)juP- o%  
    4. 在探测面计算照度 HTtGpTsF  
    5. 使用PutWorkspaceData发送照度数据到Matlab ~|B!. +  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 C&s }m0R  
    7. 用Matlab画出照度数据 f29HQhXqS  
    8. 在Matlab计算照度平均值 YV_I-l0  
    9. 返回数据到FRED中 .V)2Tz
