    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。 q0`Vw%  
    WT'P[RU2  
    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: p % 3B^  
    enableservice('AutomationServer', true) viD+~j18  
    enableservice('AutomationServer') MZ=U} &F  
    nl*{@R.q @  
    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 z\_q`43U7  
    KT{ <iz_  
    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: {8@?9Z9R{  
    1. 在FRED脚本编辑界面找到参考.  Tx/  
    2. 找到Matlab Automation Server Type Library ]=WJ%p1l  
    3. 将名字改为MLAPP 3hO` GM

    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。 `Wn0v2@a(~

    现在将脚本代码公布如下,此脚本执行如下几个步骤: C(?>l.QGw  
    1. 创建Matlab服务器。 }YU#} Ip@  
    2. 移动探测面对于前一聚焦面的位置。 c*~/[:}  
    3. 在探测面追迹光线 NZ{kjAd3c  
    4. 在探测面计算照度 {'"A hiR/  
    5. 使用PutWorkspaceData发送照度数据到Matlab lH:TE=|4  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 zi-zg Lx  
    7. 用Matlab画出照度数据 y\5V (Q\
