    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。 }g:'K  
    A$L:,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: D%6}x^`Qk  
    enableservice('AutomationServer', true) F*-'8~T  
    enableservice('AutomationServer') - b`  
    Q5_,`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 lA`-"  
    n#B}p*G  
    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: V}Oz!  O  
    1. 在FRED脚本编辑界面找到参考. *z0 R f;  
    2. 找到Matlab Automation Server Type Library 6z'0fi|EN  
    3. 将名字改为MLAPP WcpH= "vm  
    Nz%pl!

    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。 yN06` =

    现在将脚本代码公布如下,此脚本执行如下几个步骤: qLw^Qxo  
    1. 创建Matlab服务器。 fgHsg@33N  
    2. 移动探测面对于前一聚焦面的位置。 "#iO{uMWb  
    3. 在探测面追迹光线 e-.(O8  
    4. 在探测面计算照度 z]=Ks_7  
    5. 使用PutWorkspaceData发送照度数据到Matlab #MbY+[Y@v  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $U(D*0+o/  
    7. 用Matlab画出照度数据 @ ]42.oP  
    8. 在Matlab计算照度平均值 \Rha7O  
    9. 返回数据到FRED中 J%fJF//U
