    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。 AA:Ch?  
    L0/0<d(K  
    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: 9?:SxI;v  
    enableservice('AutomationServer', true) ZX sm9  
    enableservice('AutomationServer') MS%xOB*6  
    EX7gTf#  
    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 D"oyl`q  
    fT!n*;h  
    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: v<,? %(g)7  
    1. 在FRED脚本编辑界面找到参考. 40<ifz[7  
    2. 找到Matlab Automation Server Type Library {n2mh%I  
    3. 将名字改为MLAPP M;ac U~J  
    oC#@9>+@+"  
    '-p<E"#4Z  
    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。 r]iec{ ^

    现在将脚本代码公布如下,此脚本执行如下几个步骤: J GnL[9P_

    2. 移动探测面对于前一聚焦面的位置。 D:sQHJ. y  
    3. 在探测面追迹光线 gm B?L0UV  
    4. 在探测面计算照度 &EYO[~D06  
    5. 使用PutWorkspaceData发送照度数据到Matlab <\|f;7/  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 e*;-vS9H  
    7. 用Matlab画出照度数据 r4D*$H-rR  
    8. 在Matlab计算照度平均值  s de|t  
    9. 返回数据到FRED中 @[D-2s
