    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。 c!FjHlAnP  
    [#h!3d|?B  
    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: H {Wpf9_ K  
    enableservice('AutomationServer', true) Dve5m=  
        enableservice('AutomationServer')  l e/#J  
    &ZFAUE,[  
    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 c15^<6]g  
    +OP:"Q_#  
    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: D`@U[`Sw  
    1. 在FRED脚本编辑界面找到参考. SPm5tU  
    2. 找到Matlab Automation Server Type Library hl~F1"q )  
        3. 将名字改为MLAPP YU"\Wd[  
         |(8h:g  
         "TNUw&ih  
    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。 `r bqYU0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :iC\#i]6  
    1. 创建Matlab服务器。 Nm.>C4  
    2. 移动探测面对于前一聚焦面的位置。 $7 Uk;xV  
    3. 在探测面追迹光线 c|a|z}(/J  
    4. 在探测面计算照度 ]xeyXw84k  
    5. 使用PutWorkspaceData发送照度数据到Matlab L2A#OZZu  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 O lIH0  
    7. 用Matlab画出照度数据 $ T_EsnN  
    8. 在Matlab计算照度平均值 UR=s{nFd  
    9. 返回数据到FRED中 ,H1~_|)<
