    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。 oX2r?.j#M  
    zcZ^s v>  
    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: l; */M.B  
    enableservice('AutomationServer', true) NCp%sGBmG  
    enableservice('AutomationServer') cFe V?a  
    +I?Qg  
    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 P%ye$SASd  
    ))$ CEh"X  
    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:  $.=5e3  
    1. 在FRED脚本编辑界面找到参考. D_zcOq9  
    2. 找到Matlab Automation Server Type Library OrzM hQaf  
    3. 将名字改为MLAPP K T%i,T  
    P: jDB{  
    hLCsQYNDU  
    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。 9{T 8M

    现在将脚本代码公布如下,此脚本执行如下几个步骤: iz,]%<_PE  
    1. 创建Matlab服务器。 5^bh.uF  
    2. 移动探测面对于前一聚焦面的位置。 7O]J^H+7  
    3. 在探测面追迹光线 Bi %Z2/  
    4. 在探测面计算照度 ZE{aS4c  
    5. 使用PutWorkspaceData发送照度数据到Matlab ccIDMJ=2  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?=TL2"L  
    7. 用Matlab画出照度数据 "K/[[wX\b  
    8. 在Matlab计算照度平均值 "tEj`eR  
    9. 返回数据到FRED中 z&\Il#'\m+
