    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。 ^/|agQ7D2  
    Eei"baw/  
    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: o,| LO$~  
    enableservice('AutomationServer', true) Vy]y73~  
    enableservice('AutomationServer') )ZxDfRjL  
    .A;e` cKb  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 AT){OQF8&  
    V3%"z  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: `1|#Za~e  
    1. 在FRED脚本编辑界面找到参考. !PQ%h/ix  
    2. 找到Matlab Automation Server Type Library .\r=1HZ3  
    3. 将名字改为MLAPP a;=)`  
    "N"$B~W*  
    #fq%903=  
    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。 {!? @u?M

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;7id![KI4  
    1. 创建Matlab服务器。 `Gct_6  
    2. 移动探测面对于前一聚焦面的位置。 sVk+E'q  
    3. 在探测面追迹光线 ^/nj2"  
    4. 在探测面计算照度 81m3j`b  
    5. 使用PutWorkspaceData发送照度数据到Matlab G?:{9. (  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 pkW }\r  
    7. 用Matlab画出照度数据 D?+\"lI  
    8. 在Matlab计算照度平均值 Bw;gl^:UG  
    9. 返回数据到FRED中 l;*/F`>c
