    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。 m3K .\3  
    0j|JyS:}G  
    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: &!FWo@  
    enableservice('AutomationServer', true) iYxpIqWw  
    enableservice('AutomationServer') HOAgRhzE  
    , 8F(R%v  
    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 `~3y[j]kO

    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: 2r&T.  
    1. 在FRED脚本编辑界面找到参考. |nj,]pA  
    2. 找到Matlab Automation Server Type Library )[hQK_e]  
    3. 将名字改为MLAPP R~DZY{u+/$

    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。 n$y)F} .-

    现在将脚本代码公布如下,此脚本执行如下几个步骤: n$T'gX#5  
    1. 创建Matlab服务器。 =m?x|Zc_v  
    2. 移动探测面对于前一聚焦面的位置。 ta 66AEc9  
    3. 在探测面追迹光线 ;4 ON  
    4. 在探测面计算照度 2aUy1*aM  
    5. 使用PutWorkspaceData发送照度数据到Matlab RK`C31Ws  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 r8E)GBH-|  
    7. 用Matlab画出照度数据 tk <R|i  
    8. 在Matlab计算照度平均值 IZkQmA=
