    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。 I}awembw g  
    ;h#Q!M&e#  
    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: +hs:W'`%  
    enableservice('AutomationServer', true) dd4^4X`j  
    enableservice('AutomationServer') 'a~F'FN$  
    Ol;"}3*Z*  
    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 ,,?XGx  
    uTy00`1  
    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: ~b[5}_L=>  
    1. 在FRED脚本编辑界面找到参考. D8b9 T.[(  
    2. 找到Matlab Automation Server Type Library 1b@]^Ue  
    3. 将名字改为MLAPP xg;F};}5$  
    m5W':vM  
    K'[kl'  
    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。 >B.KI}dE

    现在将脚本代码公布如下,此脚本执行如下几个步骤: $6d5W=u$H  
    1. 创建Matlab服务器。 BNixp[Hc  
    2. 移动探测面对于前一聚焦面的位置。 qI[AsM+  
    3. 在探测面追迹光线 ( ;KTV*1  
    4. 在探测面计算照度 XFi9qL^  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2TQ<XHA\  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 LfvRH?<W  
    7. 用Matlab画出照度数据 g c<Y?a-  
    8. 在Matlab计算照度平均值 j(c;r>  
    9. 返回数据到FRED中 hS^8/]E={
