    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。 BD (Y =g  
    Gec?  
    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: `f~\d.*U  
    enableservice('AutomationServer', true) )* \N[zm  
        enableservice('AutomationServer')  ~;#OQ[  
    ZgP~VB0)$  
    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 6yN8 (&`  
    bI_T\Eft  
    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: zc n/LF  
    1. 在FRED脚本编辑界面找到参考. qP}187Q1  
    2. 找到Matlab Automation Server Type Library k,mgiGrQ  
        3. 将名字改为MLAPP sOY+ X  
         +nj 2  
         ^-&BGQM  
    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。 K_" denzT+

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Zr%,F[j?  
    1. 创建Matlab服务器。 nH=8I~jp  
    2. 移动探测面对于前一聚焦面的位置。 ,R~{$QUl  
    3. 在探测面追迹光线 8NJxtT~0c~  
    4. 在探测面计算照度 EL?6x  
    5. 使用PutWorkspaceData发送照度数据到Matlab b,tf]Z-  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 FZ0wtS2  
    7. 用Matlab画出照度数据 ,L.*95 ,  
    8. 在Matlab计算照度平均值 `v|w&ty*  
    9. 返回数据到FRED中 N-9Vx#i
