    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。 VfT@;B6ALF  
    7.nNz&UG]5  
    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: 3| F\a|N  
    enableservice('AutomationServer', true) mum4Uj  
    enableservice('AutomationServer') 9!,f4&G`  
    Ewa/6=]LA  
    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 C5^9D

    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: }Sh3AH/  
    1. 在FRED脚本编辑界面找到参考. [<JY[o=  
    2. 找到Matlab Automation Server Type Library 0/JTbf. CX  
    3. 将名字改为MLAPP |H'wDw8

    av>Ff6w)Y  
    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。 'R nvQ""

    1. 创建Matlab服务器。 -cB>; f)5r  
    2. 移动探测面对于前一聚焦面的位置。 DoFF<LXBt  
    3. 在探测面追迹光线 ,D93A  
    4. 在探测面计算照度 |!xqkmX  
    5. 使用PutWorkspaceData发送照度数据到Matlab Io4Ss1="  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 bb!cZ >Z  
    7. 用Matlab画出照度数据 *d}{7UMy#  
    8. 在Matlab计算照度平均值 blmY=/]  
    9. 返回数据到FRED中 /MbWS(RT
