    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。 L'=e /&  
    cyUNJw  
    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: +kCVi  
    enableservice('AutomationServer', true) f M 8kS  
        enableservice('AutomationServer') dIv/.x/V  
    '>FJk`iI  
    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 :&$4&\_F  
    oiAU}iK:  
    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: u:H@]z(x  
    1. 在FRED脚本编辑界面找到参考. 6w{^S~rqo  
    2. 找到Matlab Automation Server Type Library q|m8G  
        3. 将名字改为MLAPP wP3PI.g-g  
         Zrfp4SlZZ  
         g3{)AX[Uy  
    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。 M52kau

    现在将脚本代码公布如下,此脚本执行如下几个步骤: jeb<qi>  
    1. 创建Matlab服务器。 ~h-G  
    2. 移动探测面对于前一聚焦面的位置。 :6LOb f\01  
    3. 在探测面追迹光线 uF5d ]{Qt  
    4. 在探测面计算照度 2YK4 SL  
    5. 使用PutWorkspaceData发送照度数据到Matlab S |T:rc(~  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 /1++ 8=  
    7. 用Matlab画出照度数据 (\FjbY9&  
    8. 在Matlab计算照度平均值 dtjaQsJM^  
    9. 返回数据到FRED中 bj` cYL%
