    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。 8JLf @C:  
    o/AG9|()4  
    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: >X~B1D,SV7  
    enableservice('AutomationServer', true) ?2@^O=I  
    enableservice('AutomationServer') SioeIXU  
    `YOYC  
    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 ;c 7I "?@z  
    "Q:Gd6?h;  
    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: Q{/z>-X\x  
    1. 在FRED脚本编辑界面找到参考. H,> }t S  
    2. 找到Matlab Automation Server Type Library ,,H5zmgA  
    3. 将名字改为MLAPP tU4#7b:Y

    k+J3Kl09hM  
    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。 f) sy-o!

    1. 创建Matlab服务器。 6wlLE5  
    2. 移动探测面对于前一聚焦面的位置。 f3UCELJ  
    3. 在探测面追迹光线 jg$qp%7i%  
    4. 在探测面计算照度 EjP;P}_iK  
    5. 使用PutWorkspaceData发送照度数据到Matlab )fJ"Hq  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ~WA@YjQ]  
    7. 用Matlab画出照度数据 V]zZb-m=  
    8. 在Matlab计算照度平均值 -2hirA<^  
    9. 返回数据到FRED中 QK_5gD`$a,
