    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。 h5_G4J{1  
    6d[_G$'nk  
    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: u6V/JI}g  
    enableservice('AutomationServer', true) eK_*2=;XRW  
    enableservice('AutomationServer') OI1ud/>h  
    Qhi '') Q  
    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 5wao1sd#  
    B5V_e!*5F*  
    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: 7M_U2cd|TD  
    1. 在FRED脚本编辑界面找到参考. $0oO &)*  
    2. 找到Matlab Automation Server Type Library 8(g:HR*;  
    3. 将名字改为MLAPP 8b.u'r174

    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。 fA%z*\

    1. 创建Matlab服务器。 GDhE[of  
    2. 移动探测面对于前一聚焦面的位置。 `i) 2nNJ"  
    3. 在探测面追迹光线 LH 3}d<{  
    4. 在探测面计算照度 HjqB^|z  
    5. 使用PutWorkspaceData发送照度数据到Matlab u?Tpi[ #  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 OJN2z  
    7. 用Matlab画出照度数据 mME 4 l  
    8. 在Matlab计算照度平均值 v[@c*wo  
    9. 返回数据到FRED中 N..j{FE
