    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。 B/mYoK  
    D9.`hs0  
    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: wUoiXi09  
    enableservice('AutomationServer', true) 1?(cmXj  
    enableservice('AutomationServer') ]ni6p&b>  
    p%F8'2)}  
    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 7rcA[)<'  
    # :#M{1I  
    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: b6"}"bG  
    1. 在FRED脚本编辑界面找到参考. 87i"   
    2. 找到Matlab Automation Server Type Library thuRNYv <  
    3. 将名字改为MLAPP gE\b 982  
    ic E|.[  
    daslaa_A  
    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。 ["a"x>X&  
    %ISq>A)%

    d ;^  
    现在将脚本代码公布如下,此脚本执行如下几个步骤: bKMWWJf*'  
    1. 创建Matlab服务器。 RNTa XR+Zn  
    2. 移动探测面对于前一聚焦面的位置。 hGI+:Js6  
    3. 在探测面追迹光线 >7'+ye6z  
    4. 在探测面计算照度 SWs3SYJ\  
    5. 使用PutWorkspaceData发送照度数据到Matlab edijfhn  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 r?p[3JJ;mG  
    7. 用Matlab画出照度数据 qbiK^g R  
    8. 在Matlab计算照度平均值 WULAty  
    9. 返回数据到FRED中 XE1$K_m
