    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。 #o r7T^  
    ~U7\ LBF  
    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: QzFv;  
    enableservice('AutomationServer', true) -YRL>]1  
    enableservice('AutomationServer') 3U9+l0mBa  
    soqNzdTB2  
    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 P7>C4rmQ  
    2;?wN`}5g=  
    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: WW\)B-}T  
    1. 在FRED脚本编辑界面找到参考. QnP?;  
    2. 找到Matlab Automation Server Type Library hml\^I8Q>F  
    3. 将名字改为MLAPP H8t{ >C)]

    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。 &W!d}, ;

    现在将脚本代码公布如下,此脚本执行如下几个步骤: zIYr0k*%  
    1. 创建Matlab服务器。 P"PeL B9K  
    2. 移动探测面对于前一聚焦面的位置。 S4:\`Lo-;  
    3. 在探测面追迹光线 eR* ]<0=  
    4. 在探测面计算照度 #g`cih=QL  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]g-qWSKU  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 qiKtR  
    7. 用Matlab画出照度数据 6m{$rBR  
    8. 在Matlab计算照度平均值 z7Rcnr;  
    9. 返回数据到FRED中 w`#0 Y9O
