    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。 f@xfb ie !  
    )T$f k  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: 6{Cu~G{]N  
    enableservice('AutomationServer', true) >w]k3MC  
    enableservice('AutomationServer') YCLD!S/?  
    u;'<- _  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 #G4~]Qml  
    +y{93nl  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: wEHrer  
    1. 在FRED脚本编辑界面找到参考. O( 5L2G  
    2. 找到Matlab Automation Server Type Library t$PnQ@xu  
    3. 将名字改为MLAPP q3pN/f;kr,

    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。 0F0(]7g^

    现在将脚本代码公布如下,此脚本执行如下几个步骤: (82\&dfy  
    1. 创建Matlab服务器。 5 1CU@1Ie  
    2. 移动探测面对于前一聚焦面的位置。 $e t :  
    3. 在探测面追迹光线 dc@wf;o  
    4. 在探测面计算照度 C$re$9U  
    5. 使用PutWorkspaceData发送照度数据到Matlab X%R^)zKV  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 O^="T^J  
    7. 用Matlab画出照度数据 y\f8Ird  
    8. 在Matlab计算照度平均值 )hZ}$P1  
    9. 返回数据到FRED中 z1@sEfk>
