    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。 H?-Byi  
    _:(RkS!x  
    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:  6/u]r  
    enableservice('AutomationServer', true) }J=>nL'B  
        enableservice('AutomationServer') xi5G?r  
    bYs K|n  
    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 QH~;B[->

    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: &Pk #v  
    1. 在FRED脚本编辑界面找到参考. yjcZTvjJ  
    2. 找到Matlab Automation Server Type Library 3y#0Lb-y  
        3. 将名字改为MLAPP 1!N|a< #

         '0\,waEu  
    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。 z4CqHS~%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =|}_ASbzw  
    1. 创建Matlab服务器。 I8ZBs0sfF{  
    2. 移动探测面对于前一聚焦面的位置。 }57s  
    3. 在探测面追迹光线 NUSb7<s,&Y  
    4. 在探测面计算照度 S($8_u$U  
    5. 使用PutWorkspaceData发送照度数据到Matlab AvP$>Alc  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 *dmB Ji}  
    7. 用Matlab画出照度数据 tVI6GXH  
    8. 在Matlab计算照度平均值 dWc'RwL  
    9. 返回数据到FRED中 nZtMF%j'
