    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。 bWp40&vx  
    ~:h-m\=8Y  
    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: :yPA6O 4  
    enableservice('AutomationServer', true) MZ9{*y[z  
    enableservice('AutomationServer') U9N1 )3/u  
    ^)-* Ubzz  
    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 c;RB!`9"  
    u~ %xU~v  
    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: g$=y#<2?  
    1. 在FRED脚本编辑界面找到参考. Ekq&.qjYG"  
    2. 找到Matlab Automation Server Type Library f~bZTf  
    3. 将名字改为MLAPP & QO9/!

    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。 42 6l:>D(

    1. 创建Matlab服务器。 XLG6f(B=F  
    2. 移动探测面对于前一聚焦面的位置。 J})#43P  
    3. 在探测面追迹光线 J2tD).G  
    4. 在探测面计算照度 JQ9JWu%a  
    5. 使用PutWorkspaceData发送照度数据到Matlab BNA`Cc1VV  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 e-@=QI^,  
    7. 用Matlab画出照度数据 Ojea~Y]Sr  
    8. 在Matlab计算照度平均值 }Z^r<-N  
    9. 返回数据到FRED中 {u 7%Z}<0
