    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。 Zg2]GJP  
    Z]7tjRvq)  
    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: m'c#uU  
    enableservice('AutomationServer', true) ~\3l!zIq  
    enableservice('AutomationServer') wZ O@J|  
    N|o> %)R  
    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 Z"]xdOre  
    8M~u_`6  
    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: i!tc  
    1. 在FRED脚本编辑界面找到参考. 4NJVW+:2  
    2. 找到Matlab Automation Server Type Library 88#N~j~P  
    3. 将名字改为MLAPP OFp#<o,p  
    i"< ZVw  
    -G FwFkWm  
    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。 :Fc8S9

    1. 创建Matlab服务器。 g4i #1V=  
    2. 移动探测面对于前一聚焦面的位置。 k,A M]H  
    3. 在探测面追迹光线 n00z8B1j(l  
    4. 在探测面计算照度 4I z.fAw  
    5. 使用PutWorkspaceData发送照度数据到Matlab G%Y*q(VrEu  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 raSF3b/0  
    7. 用Matlab画出照度数据 p?}&)Un  
    8. 在Matlab计算照度平均值 )G mb? !/^  
    9. 返回数据到FRED中 =1eV
