    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。 h'VN& T,  
    hY 2nT  
    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: zRTR  
    enableservice('AutomationServer', true) W}m-5L  
    enableservice('AutomationServer') X"WKgC g$  
    Yhdt"@;..  
    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 ?#8',:  
    r @C2zF7  
    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: dmh6o *  
    1. 在FRED脚本编辑界面找到参考. ' >(])Oq,  
    2. 找到Matlab Automation Server Type Library GT\, @$r  
    3. 将名字改为MLAPP RC 7|@a  
    d"3S[_U  
    [h>|6%sW  
    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。 W>C!V

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 5G.Fi21 b  
    1. 创建Matlab服务器。 lfjY45=  
    2. 移动探测面对于前一聚焦面的位置。 rZRcy9$y>  
    3. 在探测面追迹光线 TymE(,1  
    4. 在探测面计算照度 GwiG..Y]&  
    5. 使用PutWorkspaceData发送照度数据到Matlab 3:Bwf)*  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >55c{|"@L  
    7. 用Matlab画出照度数据 a<X8l^Ln  
    8. 在Matlab计算照度平均值 DLMG<4Cd~
