    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。 ),Igu  
    [N0"mE<  
    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: a>eg H og  
    enableservice('AutomationServer', true) `FmRoMW9+  
    enableservice('AutomationServer') afye$$X  
    oEsqLh9a|  
    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 .Kssc lSD1

    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: j UB`=d|  
    1. 在FRED脚本编辑界面找到参考. &J,&>CFc  
    2. 找到Matlab Automation Server Type Library uwu`ms7z 2  
    3. 将名字改为MLAPP p;)@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。 YT<(2u#Ng

    现在将脚本代码公布如下,此脚本执行如下几个步骤: J:0`*7  
    1. 创建Matlab服务器。 _nec6=S6(  
    2. 移动探测面对于前一聚焦面的位置。 [~k!wipK  
    3. 在探测面追迹光线 -!X\xA/KN  
    4. 在探测面计算照度 vn^*  
    5. 使用PutWorkspaceData发送照度数据到Matlab qKNHhXi  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .}3K9.hkr  
    7. 用Matlab画出照度数据 }PzHtA,V
