    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。 rX1QMR7?  
    9cj9SB4  
    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: y(xJT j  
    enableservice('AutomationServer', true) G}G#i`6o  
    enableservice('AutomationServer') mN19WQ(r  
    ~B(6+~%  
    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 WH \)) y-  
    D~\$~&_]=  
    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: y? co|  
    1. 在FRED脚本编辑界面找到参考. YGsWu7dG  
    2. 找到Matlab Automation Server Type Library L{`JRu  
    3. 将名字改为MLAPP \(vY%DL1:  
    f-7 1~  
    C;vtY[}<  
    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。 )d>!"JB-

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 2m2;t0  
    1. 创建Matlab服务器。 w4d--[Q  
    2. 移动探测面对于前一聚焦面的位置。 1N>|yQz  
    3. 在探测面追迹光线 J":,Vd!*-  
    4. 在探测面计算照度 yYH0v7vx+  
    5. 使用PutWorkspaceData发送照度数据到Matlab @$+ecaVW  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 X7g1:L1Ys  
    7. 用Matlab画出照度数据 E2{FK)qT  
    8. 在Matlab计算照度平均值 <|Pun8j  
    9. 返回数据到FRED中 !dC<4qZ\C
