    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。 |!Ists  
    %U?)?iZdL  
    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: oAz<G  
    enableservice('AutomationServer', true) v{koKQ'Y()  
    enableservice('AutomationServer') wd+O5Lr.R  
    B.K4!/cF  
    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 w-FHhf

    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: voh^|(:(TH  
    1. 在FRED脚本编辑界面找到参考. SRWg[H  
    2. 找到Matlab Automation Server Type Library uV77E*+7\  
    3. 将名字改为MLAPP O`(U/?

    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。 z!Hx @){|

    现在将脚本代码公布如下,此脚本执行如下几个步骤: OjATSmZ@@  
    1. 创建Matlab服务器。 @C_ =*  
    2. 移动探测面对于前一聚焦面的位置。 4J}3,+  
    3. 在探测面追迹光线 Tf[dZ(+\  
    4. 在探测面计算照度 b1)\Zi  
    5. 使用PutWorkspaceData发送照度数据到Matlab x4 hO$3o  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 #Fzb8Yo  
    7. 用Matlab画出照度数据 VIg\]%qse  
    8. 在Matlab计算照度平均值 gh61H:tkR  
    9. 返回数据到FRED中 Z s73 ad
