    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。 : tqm2t  
    _AB9BQm  
    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: "~2#!bK7  
    enableservice('AutomationServer', true) IgR"eu U  
    enableservice('AutomationServer') :8-gm"awL5  
    >g"M.gW  
    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 ck_fEF  
    ZWhmO=b!  
    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: $#ju?B~  
    1. 在FRED脚本编辑界面找到参考. J1Ki2I=  
    2. 找到Matlab Automation Server Type Library V;hwAQbF  
    3. 将名字改为MLAPP i@R$g~~-D

    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。 (p.3'j(

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pz35trW  
    1. 创建Matlab服务器。 t-7U1B}=<C  
    2. 移动探测面对于前一聚焦面的位置。 6+B{4OY  
    3. 在探测面追迹光线 H~dHVQtJZ  
    4. 在探测面计算照度 hKZ`DB4  
    5. 使用PutWorkspaceData发送照度数据到Matlab Cq*}b4^;  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 7}cDGdr  
    7. 用Matlab画出照度数据 UUMdZ+7  
    8. 在Matlab计算照度平均值 _:Jp*z  
    9. 返回数据到FRED中 "ryk\}*<
