    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。 "0(H! }D  
    &C.{7ZNt  
    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: Sl8A=Ez  
    enableservice('AutomationServer', true) ;e>pu"#  
    enableservice('AutomationServer') k-$5H~(PZ  
    \!erP!$x .  
    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 ?4kM5NtP  
    Y'YvVI  
    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: S<f]Y4A&  
    1. 在FRED脚本编辑界面找到参考. \D9J!K82  
    2. 找到Matlab Automation Server Type Library PE IUKlX  
    3. 将名字改为MLAPP r{V=)h  
    \Tc<27-

    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。 Eu4-=2!4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ,co~@a@9  
    1. 创建Matlab服务器。 UC!?.  
    2. 移动探测面对于前一聚焦面的位置。 #^+C k HX  
    3. 在探测面追迹光线 a,GOS:?O5  
    4. 在探测面计算照度 }, < dGmkx  
    5. 使用PutWorkspaceData发送照度数据到Matlab fL #e4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8gQg#^,(t  
    7. 用Matlab画出照度数据 7wivu*0  
    8. 在Matlab计算照度平均值 ^ucmScl  
    9. 返回数据到FRED中 56;^ NE4
