    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。 /XjN%|  
    {$3j/b  
    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: _qEWu Do  
    enableservice('AutomationServer', true) AmgWj/>  
    enableservice('AutomationServer') 'G52<sF  
    VVgsLQd  
    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 zLo;.X[Y  
    #`r(zI[  
    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: OA!R5sOz"  
    1. 在FRED脚本编辑界面找到参考. <r0.ppgY  
    2. 找到Matlab Automation Server Type Library n#)PvV~  
    3. 将名字改为MLAPP 7:#  
    5FZ47m ~{Z  
    ;gdi=>S_  
    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。 (21']x

    现在将脚本代码公布如下,此脚本执行如下几个步骤: QCVsVG!sN  
    1. 创建Matlab服务器。 Lf[G>0t&n  
    2. 移动探测面对于前一聚焦面的位置。  bkxk i@t  
    3. 在探测面追迹光线 OTnu{<.a  
    4. 在探测面计算照度 h=!M6yap<  
    5. 使用PutWorkspaceData发送照度数据到Matlab GJ.kkTMT  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 {qJHL;mP:8  
    7. 用Matlab画出照度数据 z|Hy>|+  
    8. 在Matlab计算照度平均值 2O$95 M  
    9. 返回数据到FRED中 Cc@=?
