    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。 g}S%D(~  
    1:Ff#Eq,s  
    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: c>3j $D+  
    enableservice('AutomationServer', true) g6+5uvpd  
    enableservice('AutomationServer') @-Y,9mM   
    re,}}'  
    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 }u1h6rd `  
    D^a(|L3;  
    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: ~T/tk?:8Vi  
    1. 在FRED脚本编辑界面找到参考. @=%g{  
    2. 找到Matlab Automation Server Type Library /EJy?TON*  
    3. 将名字改为MLAPP < 2fy(9y

    _h`4`r  
    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。 ZmycK:f

    现在将脚本代码公布如下,此脚本执行如下几个步骤: %eh.@8GL`  
    1. 创建Matlab服务器。 B~M6l7^?  
    2. 移动探测面对于前一聚焦面的位置。 z_=V6MDM  
    3. 在探测面追迹光线 g[HuIn/  
    4. 在探测面计算照度 t BG 9Mn  
    5. 使用PutWorkspaceData发送照度数据到Matlab U(Bmffn4Z  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 x6$3 KDQm  
    7. 用Matlab画出照度数据 L4ct2|w}ul  
    8. 在Matlab计算照度平均值 \j-:5M#m  
    9. 返回数据到FRED中 ` @lNt}
