    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。  7Die FZ?  
    f)rq%N &  
    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: 5pG}Yk_(x  
    enableservice('AutomationServer', true) 5ta `%R_  
    enableservice('AutomationServer') pad*oPH,  
    %Xg4b6<9  
    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 ;;Y! ^^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: g/_5unI}u  
    1. 在FRED脚本编辑界面找到参考. ]%SH>  
    2. 找到Matlab Automation Server Type Library |i*37r6]=  
    3. 将名字改为MLAPP /62!cp/F/D

    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。 s[*rzoA

    现在将脚本代码公布如下,此脚本执行如下几个步骤: *R,5h2;  
    1. 创建Matlab服务器。 +E+p"7  
    2. 移动探测面对于前一聚焦面的位置。 C& f= ywi0  
    3. 在探测面追迹光线 }K>d+6qk5  
    4. 在探测面计算照度 ]cvwIc">  
    5. 使用PutWorkspaceData发送照度数据到Matlab *Q.>-J<S  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 i"FtcP^  
    7. 用Matlab画出照度数据 8`{:MkXP
