    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。 B|syb!g  
    &gh>'z;`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: U7LCd+Z 5X  
    enableservice('AutomationServer', true) W^W.* ?e`  
    enableservice('AutomationServer') e9\_H=t+  
    pw))9~XU  
    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 >8NUji2I  
    p>U= Jg  
    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: {DVMs|5;^  
    1. 在FRED脚本编辑界面找到参考. V%*91t_  
    2. 找到Matlab Automation Server Type Library C\[:{d  
    3. 将名字改为MLAPP asW W@E

    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。 iQ;lvOja

    1. 创建Matlab服务器。 "6~+ -_:  
    2. 移动探测面对于前一聚焦面的位置。 6XAofN/5f  
    3. 在探测面追迹光线 e[Z-&'  
    4. 在探测面计算照度 A'uubFRL2[  
    5. 使用PutWorkspaceData发送照度数据到Matlab nBd(p Oe  
    6. 使用PutFullMatrix发送标量场数据到Matlab中  >YdLB@  
    7. 用Matlab画出照度数据 8XCT[X  
    8. 在Matlab计算照度平均值 cNKGEm ;z  
    9. 返回数据到FRED中 }Oe4wEYN)
