    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。 vCNYqa)m:  
    gs|%3k|  
    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: u"n ~ 9!G  
    enableservice('AutomationServer', true) 3?(||h{  
        enableservice('AutomationServer') D&)gcO`\  
    Ol@ YSkd  
    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 M*c`@\  
    :@X@8j":  
    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: A&0sD}I\K  
    1. 在FRED脚本编辑界面找到参考. )6mv 7M{  
    2. 找到Matlab Automation Server Type Library 58My6(5y  
        3. 将名字改为MLAPP -r82'3]  
         U `"nX)$  
         A d7=JzV  
    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。 P3YG:*

         W,>;`>  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: h^0!I TL^  
    1. 创建Matlab服务器。 Z5{M_^  
    2. 移动探测面对于前一聚焦面的位置。 g<{W\VOPm  
    3. 在探测面追迹光线 Lp/]iZ@  
    4. 在探测面计算照度 akQtre`5sd  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7<?v!vQ}-  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Z)(C7,Xu  
    7. 用Matlab画出照度数据 x2TCw  
    8. 在Matlab计算照度平均值 7b T5-=.  
    9. 返回数据到FRED中 \9BIRY`
