    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+QX   
    ~@'|R%jJ  
    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: ]"/ *7NM  
    enableservice('AutomationServer', true) ?MpGz CPa  
    enableservice('AutomationServer') *2:)Rf  
    NA/+bgyuT>  
    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 `&pb`P<`

    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:  }Ecm  
    1. 在FRED脚本编辑界面找到参考. ;A- Ef  
    2. 找到Matlab Automation Server Type Library Jc:G7}j6  
    3. 将名字改为MLAPP y:2o-SJn

    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。 "Ww^?"jQ)

    现在将脚本代码公布如下,此脚本执行如下几个步骤: o,aI<5"  
    1. 创建Matlab服务器。 HH+rib'u  
    2. 移动探测面对于前一聚焦面的位置。 /OxF5 bN2  
    3. 在探测面追迹光线 4 Qw;r  
    4. 在探测面计算照度 Q7}w Y  
    5. 使用PutWorkspaceData发送照度数据到Matlab P `2Rte6s  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ImF/RKI~ "  
    7. 用Matlab画出照度数据 }:jXl!:V  
    8. 在Matlab计算照度平均值 rzl2Oj"4  
    9. 返回数据到FRED中 *-P@|eg
