    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。 !ot$Q  
    h=7eOK]  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: 0\X'a}8Bu  
    enableservice('AutomationServer', true) 'y? HF@NJ  
        enableservice('AutomationServer') WNa#X]*E)  
    ,RYahu  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 x392uS$#

    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: .>;}GsN&  
    1. 在FRED脚本编辑界面找到参考. yJMHm8OB7  
    2. 找到Matlab Automation Server Type Library }vof| (Yh  
        3. 将名字改为MLAPP K;NaiRP#k  
         MB#KLTwnT  
         -gzY ~a  
    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。 |E7)s;}D

    1. 创建Matlab服务器。 i4p2]Nr t  
    2. 移动探测面对于前一聚焦面的位置。 $mF(6<w  
    3. 在探测面追迹光线 1}#RUqFrvS  
    4. 在探测面计算照度 :{tj5P!S  
    5. 使用PutWorkspaceData发送照度数据到Matlab L(ni6-  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 XY*KWO  
    7. 用Matlab画出照度数据 |TE\]  
    8. 在Matlab计算照度平均值 Z,ZebS@yG
