    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。 X0Y1I}gD  
    f_Ma~'3   
    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: m_zl*s*6  
    enableservice('AutomationServer', true) B>rz<bPT  
    enableservice('AutomationServer') H?*EQK`7?0  
     QMLz  
    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 FkY}6  
    DDQ}&`s  
    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: Y<-h#_  
    1. 在FRED脚本编辑界面找到参考. a$r- U_?  
    2. 找到Matlab Automation Server Type Library 83K)j"!<X  
    3. 将名字改为MLAPP 4l7TrCB  
    k\BJs@-  
    g= ~Y\$&  
    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。 \(2w/~

    2. 移动探测面对于前一聚焦面的位置。 fb-Lp#!T39  
    3. 在探测面追迹光线 |0ATH`{  
    4. 在探测面计算照度 g xY6M4  
    5. 使用PutWorkspaceData发送照度数据到Matlab uzg(C#sp  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 3.+TM]RYN  
    7. 用Matlab画出照度数据 [p3{d\=*?
