    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。 i42M.M6D$  
    MHuQGc"e+4  
    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: yFD3:;}  
    enableservice('AutomationServer', true) ^PNE6  
    enableservice('AutomationServer') .nN>Ipv  
    y@T 0 jI  
    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 ^:Mal[IR  
    }!&Vcf  
    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: )&nfV5@"  
    1. 在FRED脚本编辑界面找到参考. k\ 2.\Lwb  
    2. 找到Matlab Automation Server Type Library q& :UP  
    3. 将名字改为MLAPP z'W8t|m}Pb  
    l/wdu(  
    ?!uj8&yyf  
    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。 )1EF7.|

    现在将脚本代码公布如下,此脚本执行如下几个步骤: BE#s@-zR=p  
    1. 创建Matlab服务器。 | 4slG   
    2. 移动探测面对于前一聚焦面的位置。 b3zxiq x  
    3. 在探测面追迹光线 [i9.#*  
    4. 在探测面计算照度  MeP,8,n'  
    5. 使用PutWorkspaceData发送照度数据到Matlab + YjK#  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 RF#S=X6  
    7. 用Matlab画出照度数据 K KCzq |  
    8. 在Matlab计算照度平均值 z-J?x-<  
    9. 返回数据到FRED中 <$V!y dO
