    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。 KX}dn:;(3  
    fQA)r  
    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: qJzK8eW  
    enableservice('AutomationServer', true) >2{HH\  
    enableservice('AutomationServer') RV*Zi\-X  
    K?m:.ZM  
    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 BW\5RIWwE5  
    m@2xC,@  
    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: M !XFb  
    1. 在FRED脚本编辑界面找到参考. U)1qsUDF  
    2. 找到Matlab Automation Server Type Library ~\IDg/9 Cj  
    3. 将名字改为MLAPP Q&'Nr3H#tZ  
    n#'',4f  
    3Qr!?=nf  
    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。 #]HjP\C

    现在将脚本代码公布如下,此脚本执行如下几个步骤: rbS= Ewk  
    1. 创建Matlab服务器。 IL"#TKKv  
    2. 移动探测面对于前一聚焦面的位置。  o%4+I>  
    3. 在探测面追迹光线 sU!q~`; J  
    4. 在探测面计算照度 > V}NG  
    5. 使用PutWorkspaceData发送照度数据到Matlab k<hO9;#qpL  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 _[tBLGXD  
    7. 用Matlab画出照度数据 @Odu.F1e  
    8. 在Matlab计算照度平均值 s'=]a-l~  
    9. 返回数据到FRED中 >c>ar>4xF
