    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。 4)x3!Ol  
    ?3B t ;<^  
    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: f)u*Q!BDD  
    enableservice('AutomationServer', true) |k['wqn"  
    enableservice('AutomationServer') } kh/mq  
    (Fbm9(q$d  
    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 [0**&.obz

    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: 3isXgp8  
    1. 在FRED脚本编辑界面找到参考. b]tA2~e  
    2. 找到Matlab Automation Server Type Library @4 Os?_gJ\  
    3. 将名字改为MLAPP ul z\x2[Pf

    &<fRej]v  
    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。 {"gyXDE1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ?hry=I(7r  
    1. 创建Matlab服务器。 Up!ZCZ$RC  
    2. 移动探测面对于前一聚焦面的位置。 }jyS\drJ  
    3. 在探测面追迹光线 uV/HNzC  
    4. 在探测面计算照度 Yt O@n@1  
    5. 使用PutWorkspaceData发送照度数据到Matlab =yhn8t7@]  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ()3x%3   
    7. 用Matlab画出照度数据 CL<KBmW7  
    8. 在Matlab计算照度平均值 E |GK3/  
    9. 返回数据到FRED中 b*6c. o
