    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。 i%-c/ lop  
    =k0l>)  
    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: ,!Ah+x  
    enableservice('AutomationServer', true) JqFFI:Q5a  
    enableservice('AutomationServer') |ukEnjI`u  
    :a`l_RMU  
    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 JJ[J'xl@  
    N!HiQ  
    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: ;i Ud3 '*  
    1. 在FRED脚本编辑界面找到参考. c)lMi}/  
    2. 找到Matlab Automation Server Type Library u QCQ$  
    3. 将名字改为MLAPP u*PN1E  
    Is%-r.i  
    Jd)|== yD  
    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。  +/AW6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: xNl_Q8Z?R^  
    1. 创建Matlab服务器。 "z7.i{  
    2. 移动探测面对于前一聚焦面的位置。 yPuT%H&i  
    3. 在探测面追迹光线 Vx?a&{3]-  
    4. 在探测面计算照度 -_A0<A.  
    5. 使用PutWorkspaceData发送照度数据到Matlab .PxtcC.K  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?l bK;Kv  
    7. 用Matlab画出照度数据 N "FQMxqm  
    8. 在Matlab计算照度平均值 OSsdB%bIu`  
    9. 返回数据到FRED中 uvZ|6cM
