    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。 4he GnMD  
    g)[V(yWu  
    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: n nEgx;Nl0  
    enableservice('AutomationServer', true) P )"m0Lu<  
        enableservice('AutomationServer') nNV'O(x}  
    ZF8 yw(z  
    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 N)|yu1S

    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: }'V5/>m[  
    1. 在FRED脚本编辑界面找到参考. 6vo;!V6  
    2. 找到Matlab Automation Server Type Library `2WFk8) F

    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。 L#?Ek-

    1. 创建Matlab服务器。 ]i)c{y  
    2. 移动探测面对于前一聚焦面的位置。 ]=I@1B;_m  
    3. 在探测面追迹光线 '~<m~UXvD#  
    4. 在探测面计算照度 d#Y^>"|$.  
    5. 使用PutWorkspaceData发送照度数据到Matlab (!aNq(   
        6. 使用PutFullMatrix发送标量场数据到Matlab中 LVfF[  
    7. 用Matlab画出照度数据 qPK*%Q<;  
    8. 在Matlab计算照度平均值 KnQ*vM*VM  
    9. 返回数据到FRED中 3?9IJ5p
