    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。 pA7-B>Y  
    PN}+LOD<t  
    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: }v1wpv/b(  
    enableservice('AutomationServer', true) ;!yK~OBxt  
    enableservice('AutomationServer') 337.' |ZE  
    P -m_],  
    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 ycGY5t@K@  
    *% -<Ldv  
    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: +vc+9E.?9  
    1. 在FRED脚本编辑界面找到参考. >T$0*7wF  
    2. 找到Matlab Automation Server Type Library QxT'\7f  
    3. 将名字改为MLAPP M,Gy.ivz  
    gv!8' DKn  
    !}*N';  
    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。 Ht`fC|E

    现在将脚本代码公布如下,此脚本执行如下几个步骤: l,ny=Q$[1'  
    1. 创建Matlab服务器。 l\U Q2i  
    2. 移动探测面对于前一聚焦面的位置。 j KU2  
    3. 在探测面追迹光线 `RTxc  
    4. 在探测面计算照度 !0 7jr%-~  
    5. 使用PutWorkspaceData发送照度数据到Matlab $ m`Dyu  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 G,8mFH  
    7. 用Matlab画出照度数据 dg D-"-O  
    8. 在Matlab计算照度平均值 Sn:>|y~  
    9. 返回数据到FRED中 ;W|kc</R*
