    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。 gf}*}8D  
    Sj o-Xf}  
    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: gLg.mV1<  
    enableservice('AutomationServer', true) WVz2 bzj  
        enableservice('AutomationServer') '}:(y$9.`  
    gX*j|( r  
    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 nm_4E8&X

    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: -2'+GO7G  
    1. 在FRED脚本编辑界面找到参考. n5)ml)m  
    2. 找到Matlab Automation Server Type Library EMpq+LrN  
        3. 将名字改为MLAPP q>wO=qWx  
         (" +clb`  
         ]Inu'p\  
    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。 ;- _ZWk]

    1. 创建Matlab服务器。 CugZ!>;^  
    2. 移动探测面对于前一聚焦面的位置。 YT,yRV9#  
    3. 在探测面追迹光线 /qMiv7m~Q  
    4. 在探测面计算照度 PjXiYc&  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0|C !n+OK  
        6. 使用PutFullMatrix发送标量场数据到Matlab中  Frz  
    7. 用Matlab画出照度数据 %Y"pVBc  
    8. 在Matlab计算照度平均值 lr?SL\D  
    9. 返回数据到FRED中 sLFZ 61rT
