    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。 ,G|aLBn  
    6\fMzm  
    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: "%''k~UD 4  
    enableservice('AutomationServer', true) ~+ s*\~  
        enableservice('AutomationServer') r>~d[,^$m4  
    F] ?@X  
    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 {lTxB'W@d  
    Yz-JI=  
    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: <o!&Kk9  
    1. 在FRED脚本编辑界面找到参考. 7k=F6k0)  
    2. 找到Matlab Automation Server Type Library ?koxt4 4  
        3. 将名字改为MLAPP wp %FM  
         BBR" HMa4  
         ? x"HX|n  
    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。 q@!'R{fu

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 6L,lq;  
    1. 创建Matlab服务器。  S2&9# 6  
    2. 移动探测面对于前一聚焦面的位置。 ihiuSF<NaQ  
    3. 在探测面追迹光线 J, 0pe\5  
    4. 在探测面计算照度 6b ]1d04hT  
    5. 使用PutWorkspaceData发送照度数据到Matlab p2x1xv  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 f(6UL31  
    7. 用Matlab画出照度数据 vXWsF\g  
    8. 在Matlab计算照度平均值 | 7 m5P@X  
    9. 返回数据到FRED中 s[3![ "^Y
