    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。 @xKLRw  
    74YMFI   
    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: UW7*,Bq  
    enableservice('AutomationServer', true) E~?0Yrm F  
    enableservice('AutomationServer') o -tc}Aa  
    Zw+VcZz3  
    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 &6fNPD(|  
    OE87&Cl"{t  
    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: :0,q>w  
    1. 在FRED脚本编辑界面找到参考. CZB!vh0  
    2. 找到Matlab Automation Server Type Library ;-p1z% u  
    3. 将名字改为MLAPP 6@pP aq6

    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。 } DY{>D>

    现在将脚本代码公布如下,此脚本执行如下几个步骤: vK2sj1Hzr  
    1. 创建Matlab服务器。 (.Hiee43  
    2. 移动探测面对于前一聚焦面的位置。 &$yC +cf  
    3. 在探测面追迹光线 juQ&v>9W)  
    4. 在探测面计算照度 ( ON n{12Q  
    5. 使用PutWorkspaceData发送照度数据到Matlab 4Q2=\-KFj  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 i oX [g  
    7. 用Matlab画出照度数据 `N$:QWJ  
    8. 在Matlab计算照度平均值 C?@vBM}  
    9. 返回数据到FRED中 yl|?+
