    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。 UUEDCtF)  
    0?L$)T-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: 1]3bx N  
    enableservice('AutomationServer', true) :ktX7p~  
    enableservice('AutomationServer') .W+4sax:  
    n]{}C.C=  
    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 zt?w n* _  
    z` ?xS  
    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: ZG[0rvW  
    1. 在FRED脚本编辑界面找到参考. fu "z%h]   
    2. 找到Matlab Automation Server Type Library @k #y-/~?  
    3. 将名字改为MLAPP >E,L"&_j  
     p|8Fl  
    ]:#$6D"  
    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。 __n"DLW

    现在将脚本代码公布如下,此脚本执行如下几个步骤: COL8YY  
    1. 创建Matlab服务器。 }N9a!,{P=b  
    2. 移动探测面对于前一聚焦面的位置。 S_-mmzC(  
    3. 在探测面追迹光线 L#@$Mtc  
    4. 在探测面计算照度 k 5r*?Os  
    5. 使用PutWorkspaceData发送照度数据到Matlab b`Ek;nYek  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 >)Z2bCe  
    7. 用Matlab画出照度数据 O xaua  
    8. 在Matlab计算照度平均值 N)y;owgo  
    9. 返回数据到FRED中 ~HI0<;r=eL
