    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。 P!R`b9_U  
    f 0/q{*  
    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: q ) e* eN  
    enableservice('AutomationServer', true)  o^d  
    enableservice('AutomationServer') BS?rKtdm(  
    X-yS9E  
    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 Jlx

    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: JGlp7wro  
    1. 在FRED脚本编辑界面找到参考. 4g+o/+6!4  
    2. 找到Matlab Automation Server Type Library 7$kTeKiP  
    3. 将名字改为MLAPP V4<f4|IL  
    q] '2'"k  
    xy^z_`  
    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。 {>yy3(N

    现在将脚本代码公布如下,此脚本执行如下几个步骤: NE?tfj  
    1. 创建Matlab服务器。 !$0ozDmD  
    2. 移动探测面对于前一聚焦面的位置。 ;C5 J ^xHI  
    3. 在探测面追迹光线 I5E4mv0<i  
    4. 在探测面计算照度 239g pf]}  
    5. 使用PutWorkspaceData发送照度数据到Matlab 3Q#3S  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ou\~^  
    7. 用Matlab画出照度数据 l Ztw[c  
    8. 在Matlab计算照度平均值 JIMi~mEiN  
    9. 返回数据到FRED中 Mgux (5`;
