    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。 k@|Go )~  
    l}_6 _g>6  
    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: VM}7 ~  
    enableservice('AutomationServer', true) 4vJg"*?  
    enableservice('AutomationServer') L/xTW  
    }!QVcu"+t/  
    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 b_w(F_0

    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: h|%a}])G)  
    1. 在FRED脚本编辑界面找到参考. uN@El1ouY  
    2. 找到Matlab Automation Server Type Library 4`/Td?THx  
    3. 将名字改为MLAPP srK9B0I

    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。 ,FL*Z9wA

    1. 创建Matlab服务器。 q$'D}OHT  
    2. 移动探测面对于前一聚焦面的位置。 ZVz`g]  
    3. 在探测面追迹光线 5S 4 Bz  
    4. 在探测面计算照度 g4^3H3Pd  
    5. 使用PutWorkspaceData发送照度数据到Matlab Jd28/X5&  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 R1~wzy  
    7. 用Matlab画出照度数据 B &e'n<  
    8. 在Matlab计算照度平均值 3QDz9KwCAw  
    9. 返回数据到FRED中 Ya;y@44
