    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。 .wmqaLd%  
    6`vW4]zu  
    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: B,&QI&k`~  
    enableservice('AutomationServer', true) 7>f"4r_r6<  
    enableservice('AutomationServer') ?20R\ ]U  
    ?;H}5>^8P  
    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 " Zx<hL*  
    ~A1!!rJX  
    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: V#5$J Xp  
    1. 在FRED脚本编辑界面找到参考. $:\`E 56\  
    2. 找到Matlab Automation Server Type Library @OGG]0 J  
    3. 将名字改为MLAPP P -nhG  
    Dx`-h#  
    q3#+G:nh  
    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。 &r~s3S{pQ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 15q^&l[Q  
    1. 创建Matlab服务器。 jd,i=P%  
    2. 移动探测面对于前一聚焦面的位置。 ZHa>8x;Mjl  
    3. 在探测面追迹光线 6}?d%K  
    4. 在探测面计算照度 01n132k  
    5. 使用PutWorkspaceData发送照度数据到Matlab cs ?WE9N  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 > <Zu+HX  
    7. 用Matlab画出照度数据 lSW'qgh  
    8. 在Matlab计算照度平均值 k].swvIi  
    9. 返回数据到FRED中 aidQ,(PDj
