    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。 .{ -C*  
    =H)"t:xE  
    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: T^1]|P  
    enableservice('AutomationServer', true) *L+)R*|:&  
        enableservice('AutomationServer') n~C!PXE  
    t(Sjo8, b  
    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 mZ! 1Vh

    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: R\ZyS )~l  
    1. 在FRED脚本编辑界面找到参考. 72akOx   
    2. 找到Matlab Automation Server Type Library qrt2BT)  
        3. 将名字改为MLAPP [ m#|[%  
         |4?O4QN  
         Fo$'*(i  
    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。 IWs)n1D*]

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Kq4b`cn{_  
    1. 创建Matlab服务器。 Api<q2@R  
    2. 移动探测面对于前一聚焦面的位置。 rJws#^ ]  
    3. 在探测面追迹光线 s!eB8lkcT  
    4. 在探测面计算照度 @yxF/eeEy+  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0.kQqy~5  
        6. 使用PutFullMatrix发送标量场数据到Matlab中  _7P#?:h  
    7. 用Matlab画出照度数据 N2/t  
    8. 在Matlab计算照度平均值 R0DWjN$j  
    9. 返回数据到FRED中 DB>.Uf"
