    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。 K:5eek  
    $%2H6Eg0  
    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: "T6#  
    enableservice('AutomationServer', true) N.j "S'(i  
    enableservice('AutomationServer') bAF )Bli  
    lKV"Mh+6  
    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 wW`}VKu  
    F}X0',   
    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: mBk5+KyT  
    1. 在FRED脚本编辑界面找到参考. !/I0i8T  
    2. 找到Matlab Automation Server Type Library 4TRG.$2[  
    3. 将名字改为MLAPP qpqokK  
    Bjj<\8 ^M  
    5bX6#5uP1  
    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。 9 E1W|KE

    现在将脚本代码公布如下,此脚本执行如下几个步骤: r;qzo .  
    1. 创建Matlab服务器。 j+^L~, S  
    2. 移动探测面对于前一聚焦面的位置。 1BTIJ Gw  
    3. 在探测面追迹光线 7#2j>G{?]v  
    4. 在探测面计算照度 '2^ Yw  
    5. 使用PutWorkspaceData发送照度数据到Matlab F u _@!K  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 smU4jh9S  
    7. 用Matlab画出照度数据 'Ud| Ex@A9  
    8. 在Matlab计算照度平均值 ..KwTf  
    9. 返回数据到FRED中 F^kwdS
