    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。 LE5.b]tv2  
    SG}V[Glk  
    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: Xs&TJ8a  
    enableservice('AutomationServer', true) MV_Srz  
    enableservice('AutomationServer') :j|IP)-f  
    ES~^M840f  
    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 NK|?y  
    ^ -FX  
    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: Ol"3a|  
    1. 在FRED脚本编辑界面找到参考. ZyOv.,y  
    2. 找到Matlab Automation Server Type Library 8[r9HC  
    3. 将名字改为MLAPP J PyOG _h  
    ,B4VT 96*  
    }X GEX:1K  
    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。 +3s%E{

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Hf'G8vW  
    1. 创建Matlab服务器。 ,+`61J3W  
    2. 移动探测面对于前一聚焦面的位置。 .@ xF6UZ  
    3. 在探测面追迹光线 x21dku<6K[  
    4. 在探测面计算照度 %Qg+R26U  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5es[Ph|K5  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 :o:e,WKxb  
    7. 用Matlab画出照度数据 dz~co Z9  
    8. 在Matlab计算照度平均值 iAT)VQ&  
    9. 返回数据到FRED中 2G$SpfeIu
