    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。 kty,hAXe  
    pPG@_9qf  
    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: "lf_`4  
    enableservice('AutomationServer', true) (A*r&Ak[  
        enableservice('AutomationServer') rS 4'@a  
    &xqe8!FeA  
    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 #:68}f"$

    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: 32IN;X|  
    1. 在FRED脚本编辑界面找到参考. F*d{<  
    2. 找到Matlab Automation Server Type Library 1*x4T%RF$  
        3. 将名字改为MLAPP EtH)E)

         ^~5tntb.  
    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。 LE Y Y{G?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: =k[!p'~jD  
    1. 创建Matlab服务器。 *0R=(Gy  
    2. 移动探测面对于前一聚焦面的位置。 ^aZ Wu|p  
    3. 在探测面追迹光线 Z3R..vy8  
    4. 在探测面计算照度 *qG=p`  
    5. 使用PutWorkspaceData发送照度数据到Matlab |"P5%k#6^>  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 *k'9 %'<  
    7. 用Matlab画出照度数据 7@DinA!  
    8. 在Matlab计算照度平均值 T"Q4vk,3*J  
    9. 返回数据到FRED中 BsB}noN}
