    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。 vP,WV9Q1u  
    #jDO?Y Sa  
    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: WZFV8'  
    enableservice('AutomationServer', true) 7[u&%  
    enableservice('AutomationServer') 4~o\Os+8  
    Gi{1u}-0  
    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 *&5G+d2  
    Nc;7KMOIA  
    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: F." L{g  
    1. 在FRED脚本编辑界面找到参考. :+-s7'!4  
    2. 找到Matlab Automation Server Type Library FEdyh?$  
    3. 将名字改为MLAPP q=[0`--cd  
    $1?YVA7  
    E )Hp.  
    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。 kkd<CEz2IM

    现在将脚本代码公布如下,此脚本执行如下几个步骤: x&;{4F Nw  
    1. 创建Matlab服务器。 bgEUG  
    2. 移动探测面对于前一聚焦面的位置。 pD &\Z~5T  
    3. 在探测面追迹光线 W cqYpPv  
    4. 在探测面计算照度 ~Q6ufTGhpM  
    5. 使用PutWorkspaceData发送照度数据到Matlab hwC3['  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 y<#y3M!\  
    7. 用Matlab画出照度数据 T1e}WJbFE  
    8. 在Matlab计算照度平均值 RrRCT.+E  
    9. 返回数据到FRED中 <X;y 4lPZ
