    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。 k iu#THF  
    z-m:l;  
    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: 7ZFd;-  
    enableservice('AutomationServer', true) (r/))I9^  
    enableservice('AutomationServer') 8gW$\  
     Sr+ &  
    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 +\RviF[+  
    VLC=>w\,  
    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: q3ebps9^  
    1. 在FRED脚本编辑界面找到参考. l}W"> yQ0  
    2. 找到Matlab Automation Server Type Library E&0]s  
    3. 将名字改为MLAPP @+hO,WXN  
    :.crES7<[X  
    &:#"APX  
    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。 P(B&*1X

    现在将脚本代码公布如下,此脚本执行如下几个步骤: YbJB.;qK  
    1. 创建Matlab服务器。 3^]Kd  
    2. 移动探测面对于前一聚焦面的位置。 }@vf=jm>  
    3. 在探测面追迹光线 / gP"X1.  
    4. 在探测面计算照度 K Vnz{cx`  
    5. 使用PutWorkspaceData发送照度数据到Matlab 6t'vzcQs  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $u, ~183  
    7. 用Matlab画出照度数据 mV|Z5= f  
    8. 在Matlab计算照度平均值 M<ba+Qn$  
    9. 返回数据到FRED中 Ur(<  ]
