    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。 "St,4 b  
    K.l?R#G`,F  
    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: S 5m1~fz  
    enableservice('AutomationServer', true) g"# R>&P  
    enableservice('AutomationServer') YDjQ&EH  
    f_D1zU^  
    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 vx!nC}f"k`  
    IO^O9IEx,  
    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: w4(DR?[nC  
    1. 在FRED脚本编辑界面找到参考. bhe|q`1,E  
    2. 找到Matlab Automation Server Type Library Qkr'C n  
    3. 将名字改为MLAPP qZ_^#%zO

    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。 A "_;.e`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 8.Y6r  
    1. 创建Matlab服务器。 [.Kia >  
    2. 移动探测面对于前一聚焦面的位置。 2{+\\.4Evk  
    3. 在探测面追迹光线 l<7 b  
    4. 在探测面计算照度 VCbnS191*  
    5. 使用PutWorkspaceData发送照度数据到Matlab .O1g'%  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 er l_Gg  
    7. 用Matlab画出照度数据 &)xoR4!2  
    8. 在Matlab计算照度平均值 5f}63as  
    9. 返回数据到FRED中 2&$A x
