    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。 IHac:=*Q  
     =j]<t  
    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: 6<QQ@5_  
    enableservice('AutomationServer', true) $qnZl'O>  
    enableservice('AutomationServer') oLeq!K}re  
    sY&IquK^  
    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 Ee! 4xg

    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: =8. ,43+  
    1. 在FRED脚本编辑界面找到参考. T.BW H2gRP  
    2. 找到Matlab Automation Server Type Library aB&&YlR=n<  
    3. 将名字改为MLAPP *] ) `z8Ox

    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。 EV%gF

    1. 创建Matlab服务器。 f.$af4 u  
    2. 移动探测面对于前一聚焦面的位置。 'zTLl8P  
    3. 在探测面追迹光线 k?^z;Tlvw  
    4. 在探测面计算照度 (hbyEQhF  
    5. 使用PutWorkspaceData发送照度数据到Matlab #)O6 5GI  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 S4z;7z(8+  
    7. 用Matlab画出照度数据 `Ggbi4),  
    8. 在Matlab计算照度平均值 + =</&Tm  
    9. 返回数据到FRED中 @# l= l
