    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。 Ydh+iLjhx  
    _{y4N0  
    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: yMKVF`D*  
    enableservice('AutomationServer', true) vQ1#Zg y  
    enableservice('AutomationServer') sx@ %3j  
    ?9:~d#p  
    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 YG#.L}X@C  
    9wpV} .(  
    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_-V?7  
    1. 在FRED脚本编辑界面找到参考. 75*q^ui  
    2. 找到Matlab Automation Server Type Library QK(w2`  
    3. 将名字改为MLAPP Ec l/2  
    L31#v$;4  
    05Y4=7,!  
    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。 ;.&k zzvJ

    1. 创建Matlab服务器。 ExZ|_7^<  
    2. 移动探测面对于前一聚焦面的位置。 ?j@(1",=&  
    3. 在探测面追迹光线 w)xfP^M#  
    4. 在探测面计算照度 @ACq:+/Q c  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,w$:=;i  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "aJf W  
    7. 用Matlab画出照度数据 V D.T=(  
    8. 在Matlab计算照度平均值 whh#J (  
    9. 返回数据到FRED中 D> EN:_v
