    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。 JZ/O0PW  
    o!`O i5  
    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: _`i%9Ad.4  
    enableservice('AutomationServer', true) Fx5d@WNa>  
    enableservice('AutomationServer') qO{ ZZ*  
    aGb. Lh9  
    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 Tw;qY  
    3DC%I79  
    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: VHr7GAmU  
    1. 在FRED脚本编辑界面找到参考. 9zYiG3 d  
    2. 找到Matlab Automation Server Type Library T% 13 '  
    3. 将名字改为MLAPP (0#F]""\e  
    QM_X2Ho  
    UvJuOh+  
    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。 #0hNk%X=

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Q&7)vs  
    1. 创建Matlab服务器。 o 7W Kh=  
    2. 移动探测面对于前一聚焦面的位置。 tQ/ #t<4D  
    3. 在探测面追迹光线 aq+IC@O  
    4. 在探测面计算照度 yISQYvSN  
    5. 使用PutWorkspaceData发送照度数据到Matlab E? eWv)//  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 D`:d'ow~KQ  
    7. 用Matlab画出照度数据 3'*%R48P`  
    8. 在Matlab计算照度平均值 Ocwp]Mut&  
    9. 返回数据到FRED中 b>= Wq
