    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。 [$ejp>'Ud  
    TJ1+g \  
    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: KN7n@$8YM  
    enableservice('AutomationServer', true) j{Txl\D>  
    enableservice('AutomationServer')  }(1JaG  
    %Mk0QKzUo  
    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 |m80]@>  
    v7DE  
    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: V( -mD  
    1. 在FRED脚本编辑界面找到参考. *7h!w!LN~  
    2. 找到Matlab Automation Server Type Library 4*'pl.rb>  
    3. 将名字改为MLAPP hED=u/ql[

    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。 aEWWFN

    现在将脚本代码公布如下,此脚本执行如下几个步骤: >&p0d0  
    1. 创建Matlab服务器。 ^",ACWF4Sk  
    2. 移动探测面对于前一聚焦面的位置。 Ygl%eP%Z  
    3. 在探测面追迹光线 l?Fb ='#  
    4. 在探测面计算照度 `/~8}Y{  
    5. 使用PutWorkspaceData发送照度数据到Matlab JM\m)RH0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 GF5^\Rf  
    7. 用Matlab画出照度数据 aMvI?y {  
    8. 在Matlab计算照度平均值 _<NMyRJo  
    9. 返回数据到FRED中 o4zM)\;F
