    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。 Joq9.%7Q  
    =<O{  
    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: FhAuTZk  
    enableservice('AutomationServer', true) HSp*lHU  
    enableservice('AutomationServer') !);}zW!  
    t*e+[  
    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 G-bG}9vc]  
    ^yH|k@y  
    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: VXR.2C  
    1. 在FRED脚本编辑界面找到参考.  U7tT  
    2. 找到Matlab Automation Server Type Library o(C({]UO/  
    3. 将名字改为MLAPP ldanM>5  
    bq<QUw=]q&  
    I?s)^'  
    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。 /Eh\07p

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 'rp(k\ pY  
    1. 创建Matlab服务器。 wL5IAkq  
    2. 移动探测面对于前一聚焦面的位置。 0ydAdgD  
    3. 在探测面追迹光线 zu^?9k  
    4. 在探测面计算照度 =n9adq  
    5. 使用PutWorkspaceData发送照度数据到Matlab HBo^8wN  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 E' JVf%)  
    7. 用Matlab画出照度数据 4#;rv$ {  
    8. 在Matlab计算照度平均值  L~I<y;x  
    9. 返回数据到FRED中 g%1!YvS3v
