    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。 KZPEG!-5  
    e{Z &d  
    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: \W1/p`  
    enableservice('AutomationServer', true) )>BHL3@  
    enableservice('AutomationServer') YuB+k^  
    W`^@)|9^)  
    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 +^;JS3p@\  
    $AHQmyg<  
    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: *hcYGLx r  
    1. 在FRED脚本编辑界面找到参考. >M&3Y XC  
    2. 找到Matlab Automation Server Type Library P;4w*((} ~  
    3. 将名字改为MLAPP fFQ|T:vm  
    k5]j.V2f  
    `p+Zz"/  
    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。 .bio7c6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: dO%W+K  
    1. 创建Matlab服务器。 7g3 >jh  
    2. 移动探测面对于前一聚焦面的位置。 /hO1QT}xd  
    3. 在探测面追迹光线 GgKEP,O  
    4. 在探测面计算照度 5ZBKRu  
    5. 使用PutWorkspaceData发送照度数据到Matlab 2WG>, 4W2  
    6. 使用PutFullMatrix发送标量场数据到Matlab中  W%\C_  
    7. 用Matlab画出照度数据 fDLG>rXPT  
    8. 在Matlab计算照度平均值 5xL~`-IA&v  
    9. 返回数据到FRED中 }NB}"%2
