    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。 A,=l9hE'  
    H+ M ~|Ju7  
    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: *v5y]E%aW  
    enableservice('AutomationServer', true) /?6y2t  
    enableservice('AutomationServer') }Ql;%7  
    cxv) LOl-  
    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 3<`h/`ku  
    bg=`   
    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: 92tb`'  
    1. 在FRED脚本编辑界面找到参考. 4@W.{|2~  
    2. 找到Matlab Automation Server Type Library zYs? w=  
    3. 将名字改为MLAPP *l9Y]hinq

    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。 eb8_guZ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Uis P 8/k  
    1. 创建Matlab服务器。 Rd!.8K[  
    2. 移动探测面对于前一聚焦面的位置。 $fn^i.  
    3. 在探测面追迹光线 $N ]P#g?Q  
    4. 在探测面计算照度 wGxLs>| 4  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;s!H  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 v m$v[  
    7. 用Matlab画出照度数据 M<L<mP}  
    8. 在Matlab计算照度平均值 Fca?'^X  
    9. 返回数据到FRED中 [&4y@
