    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。 UKdzJEhG  
    SqLKF<tY]/  
    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: :nn'>  
    enableservice('AutomationServer', true) 2TO1i0  
    enableservice('AutomationServer') Y-9F*8<  
    Ex{]<6UAu  
    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 K,Vl.-4?  
    _`_$U MK;  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: y+_U6rv[  
    1. 在FRED脚本编辑界面找到参考. A}o1I1+  
    2. 找到Matlab Automation Server Type Library \hVFK6  
    3. 将名字改为MLAPP 6\L,L &  
    {1 mD(+pJ{  
    {$JIR}4S  
    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。 H}/1/5 L

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pbNVj~#6  
    1. 创建Matlab服务器。 {Ffr l(*  
    2. 移动探测面对于前一聚焦面的位置。 uQ}kq7gd  
    3. 在探测面追迹光线 43YusUv  
    4. 在探测面计算照度 fQ@["b   
    5. 使用PutWorkspaceData发送照度数据到Matlab k 'o?/  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Gvwel!6  
    7. 用Matlab画出照度数据 bk|>a=o3  
    8. 在Matlab计算照度平均值 ]`x~v4JU  
    9. 返回数据到FRED中 ]dH; +3 }
