    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。 ? xs0J  
     S_6;e|  
    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: VG^-aR_F  
    enableservice('AutomationServer', true) \59hW%Di  
    enableservice('AutomationServer') vX%gcs/@  
    3!x)LUWfWY  
    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 P.7B]&T6  
    c6|&?}F  
    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: \I]'6N=  
    1. 在FRED脚本编辑界面找到参考. tDkqwF),  
    2. 找到Matlab Automation Server Type Library =;T[2:JUu  
    3. 将名字改为MLAPP ma~`&\xE

    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。 VGIc|Q=F

    现在将脚本代码公布如下,此脚本执行如下几个步骤: f*Bc`+G  
    1. 创建Matlab服务器。 w@We,FUJN  
    2. 移动探测面对于前一聚焦面的位置。 i/Z5/(zF  
    3. 在探测面追迹光线 uzD{ewR/.y  
    4. 在探测面计算照度 7Cjrh"al"  
    5. 使用PutWorkspaceData发送照度数据到Matlab {HeMdGn9  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~Ua0pS?  
    7. 用Matlab画出照度数据 tA.C"  
    8. 在Matlab计算照度平均值 #'P&L>6 ;  
    9. 返回数据到FRED中 x1h!_^(QfF
