    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。 uEkGo5  
    <2wC)l3j*  
    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: 10tTV3`IM  
    enableservice('AutomationServer', true) 7?8+h  
    enableservice('AutomationServer') 9TEAM<b;  
    [Bj\h7 G  
    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 pxCQ=0k  
    4}0Ry\ 6  
    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!*T)\  
    1. 在FRED脚本编辑界面找到参考. 3pyE'9"f6  
    2. 找到Matlab Automation Server Type Library [buLo*C4:  
    3. 将名字改为MLAPP eL [.;_  
    _jaB[Q=By  
    0Kg?X  
    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。 mNJCV8 <

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 3~Ll<8fv  
    1. 创建Matlab服务器。 HT6$|j  
    2. 移动探测面对于前一聚焦面的位置。 :g{ybTSEe  
    3. 在探测面追迹光线 biRkq c;  
    4. 在探测面计算照度 ?>My&yB  
    5. 使用PutWorkspaceData发送照度数据到Matlab wWM[Hus  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 8_M"lU0[  
    7. 用Matlab画出照度数据 Ged} qXn  
    8. 在Matlab计算照度平均值 4r#4h4`y|  
    9. 返回数据到FRED中 *]c~[&x5&
