    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。 #gaQaUjR  
    b}w C|\s  
    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: N0w`!<y:c  
    enableservice('AutomationServer', true) ym/fFm6h  
    enableservice('AutomationServer') #D9e$E(J^  
    KdUnD4d  
    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 qdG~!h7j  
    L9ap(  
    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: NU\ 5{N<  
    1. 在FRED脚本编辑界面找到参考. q@~L&{  
    2. 找到Matlab Automation Server Type Library |*X*n*oI  
    3. 将名字改为MLAPP + "}=d3E6

    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。 -;XKcS7Ue

    现在将脚本代码公布如下,此脚本执行如下几个步骤: u=NS sTP&  
    1. 创建Matlab服务器。 /.eeO k  
    2. 移动探测面对于前一聚焦面的位置。 \[>9UC%  
    3. 在探测面追迹光线 =GBI0&U  
    4. 在探测面计算照度 `L5~mb;7*  
    5. 使用PutWorkspaceData发送照度数据到Matlab f8<o8*`7  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $ RwB_F  
    7. 用Matlab画出照度数据 ORWm C!  
    8. 在Matlab计算照度平均值 $hVYTy~}  
    9. 返回数据到FRED中 cZ+7.oDu
