    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。 d&fENnt?h  
    ' ft  |  
    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: 8z+ CYeV  
    enableservice('AutomationServer', true) m\t %wr  
    enableservice('AutomationServer') m^ILcp!  
    SZgH0W("L  
    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 A}%sF MA  
    {U4%aoBd8  
    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: Oz+>I ^Q  
    1. 在FRED脚本编辑界面找到参考. ie_wJ=s  
    2. 找到Matlab Automation Server Type Library wk3yz6V2  
    3. 将名字改为MLAPP ''V:+@Toh

    X<1# )xC  
    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。 q H+~rj

    现在将脚本代码公布如下,此脚本执行如下几个步骤: rod{77  
    1. 创建Matlab服务器。 S]<Hx_[}  
    2. 移动探测面对于前一聚焦面的位置。 I|p(8 R!  
    3. 在探测面追迹光线 /JvNJ f  
    4. 在探测面计算照度 $idYG<],  
    5. 使用PutWorkspaceData发送照度数据到Matlab Kj'uTEM  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $Q ?<']|A  
    7. 用Matlab画出照度数据 P'g$F<~V  
    8. 在Matlab计算照度平均值 ,fL*yn  
    9. 返回数据到FRED中 n\d-^ml
