    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。 5L"{J5R}  
    a(NN%'fDD  
    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: 8 POrD8B  
    enableservice('AutomationServer', true) }.$oZo9J  
    enableservice('AutomationServer') IFH%R>={  
    _}EGk4E  
    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 Gnr]qxL

    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: ABSA le  
    1. 在FRED脚本编辑界面找到参考. ;KWR/?ec  
    2. 找到Matlab Automation Server Type Library d /+sR@\  
    3. 将名字改为MLAPP w t? 8-_

    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。 5Q^ L"&0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Xl.h&x0? 8  
    1. 创建Matlab服务器。 hT>h  
    2. 移动探测面对于前一聚焦面的位置。 &^8>Kd8  
    3. 在探测面追迹光线 O{,Uge2n,  
    4. 在探测面计算照度 uB>NwCL;  
    5. 使用PutWorkspaceData发送照度数据到Matlab Ny /bNQS  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 MRZ Wfc  
    7. 用Matlab画出照度数据 $M@SZknm  
    8. 在Matlab计算照度平均值 @f{yx\u/  
    9. 返回数据到FRED中 P>z k
