    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。 JTdK\A>l  
    R1?g6. Mq  
    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: ^${-^w@,%V  
    enableservice('AutomationServer', true) %#"uK:(N  
    enableservice('AutomationServer') 6nxf <1  
    Lt=#tu&d  
    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 nuXaZRH

    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: wgI$'tI  
    1. 在FRED脚本编辑界面找到参考. E]"ePdZZ/  
    2. 找到Matlab Automation Server Type Library 9e.n1  
    3. 将名字改为MLAPP 5P+3D{  
    ]xV7)/b5G  
    :m-HHWMN  
    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。 ?6~RGg

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Y#C=ku  
    1. 创建Matlab服务器。 +5 @8't  
    2. 移动探测面对于前一聚焦面的位置。 d0IHl!X  
    3. 在探测面追迹光线 9KD2C>d<  
    4. 在探测面计算照度 O{LWQ"@y  
    5. 使用PutWorkspaceData发送照度数据到Matlab L +-B,466  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 O!uX:TE|Q  
    7. 用Matlab画出照度数据 o^_z+JFwb  
    8. 在Matlab计算照度平均值 TQYud'u/  
    9. 返回数据到FRED中 8h-6;x^^
