    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。 5''*UFIF1  
    pL oy  
    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: g+q@i{Yn  
    enableservice('AutomationServer', true) .I?@o8'x  
    enableservice('AutomationServer') A,i()R'I  
    ^. X[)U  
    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 U/MFhD(06  
    ~HLRfL?  
    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: 5?u[XAE  
    1. 在FRED脚本编辑界面找到参考. Qb^q+C)o]  
    2. 找到Matlab Automation Server Type Library H;_yRUY9  
    3. 将名字改为MLAPP GA^mgm"O  
    L0Vgo<A  
    H^c0Kh+  
    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。 #*IVlchA"B

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pD`/_-=^h  
    1. 创建Matlab服务器。 H;vZm[\0N-  
    2. 移动探测面对于前一聚焦面的位置。 }*;EFR6'  
    3. 在探测面追迹光线 =v2%Vs\7k  
    4. 在探测面计算照度 \&|CM8A  
    5. 使用PutWorkspaceData发送照度数据到Matlab MB$a82bY  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 f>iuHR*EXB  
    7. 用Matlab画出照度数据 =DgC C|p  
    8. 在Matlab计算照度平均值 !c8L[/L  
    9. 返回数据到FRED中 4^Qi2[w
