    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。 mA=i)Ga  
    ={xE!"  
    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: uPl\I6k  
    enableservice('AutomationServer', true) #Q`dku%V:  
    enableservice('AutomationServer') O|M{-)  
    SrK)t.oK  
    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 k>g _Z`%<  
    5w@4:$=I  
    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: -xA2pYz"  
    1. 在FRED脚本编辑界面找到参考. |VNnOM  
    2. 找到Matlab Automation Server Type Library 07^iP>?  
    3. 将名字改为MLAPP } =]M2}

    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。 [6XF=L,!

    现在将脚本代码公布如下,此脚本执行如下几个步骤: J\M>33zu  
    1. 创建Matlab服务器。 7*Ej. HK  
    2. 移动探测面对于前一聚焦面的位置。 *5^Q7``  
    3. 在探测面追迹光线 ~,B5Hc 2  
    4. 在探测面计算照度 DuHu\>f<S  
    5. 使用PutWorkspaceData发送照度数据到Matlab j4R(B  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 4QIX19{"  
    7. 用Matlab画出照度数据 ?3.b{Cq{-  
    8. 在Matlab计算照度平均值 #kaY0M  
    9. 返回数据到FRED中 OD6\Mr2=
