    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。 2{ l|<'  
    |cuKC \  
    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: 3rN}iSF^  
    enableservice('AutomationServer', true) \Jc}Hzug  
    enableservice('AutomationServer') uuh._H}-  
    Vx5fQ mx  
    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 XrMw$_0)  
    NgsEEPu?  
    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: zZ51jA9x  
    1. 在FRED脚本编辑界面找到参考. g co;8e_  
    2. 找到Matlab Automation Server Type Library Z RwN#?x  
    3. 将名字改为MLAPP 0%HAa|L,,  
    #a|r ^%D  
    'ju_l)(R  
    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。 Unt]=S3u

    现在将脚本代码公布如下,此脚本执行如下几个步骤: -cn`D2RP  
    1. 创建Matlab服务器。 ?/,V{!UTtq  
    2. 移动探测面对于前一聚焦面的位置。 oL>o*/  
    3. 在探测面追迹光线 2p 7;v7)y  
    4. 在探测面计算照度 zt|1tU:  
    5. 使用PutWorkspaceData发送照度数据到Matlab yF |28KJ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 r~,3  
    7. 用Matlab画出照度数据 apM)$  
    8. 在Matlab计算照度平均值 :]8A;`G}  
    9. 返回数据到FRED中 *N{k#d/
