    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。 n{sF'n</  
    |Iei!jm  
    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: A|>~/OW=@  
    enableservice('AutomationServer', true) l~P%mVC3m  
    enableservice('AutomationServer') s2=rj?g&(X  
    PyQt8Qlz  
    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 K8[vJ7(!|  
    w#|uR^~  
    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: iUDNm|e  
    1. 在FRED脚本编辑界面找到参考. |a9d]^  
    2. 找到Matlab Automation Server Type Library fA"N5qQI(  
    3. 将名字改为MLAPP $yxwB/O(  
    }e$^v*16  
    tt5t(+5j  
    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。 ipzv]c&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: :/YHU3~Y  
    1. 创建Matlab服务器。 .. jc^'L  
    2. 移动探测面对于前一聚焦面的位置。 qw^kA?  
    3. 在探测面追迹光线 We%HdTKT  
    4. 在探测面计算照度 .\Gl)W  
    5. 使用PutWorkspaceData发送照度数据到Matlab 8<V6W F`e  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 38ac~1HjE  
    7. 用Matlab画出照度数据 {A!1s;  
    8. 在Matlab计算照度平均值 l~ 3H"  
    9. 返回数据到FRED中 r'bctFsD
