    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。 HG{r\jh  
    S2T~7-  
    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$  
    enableservice('AutomationServer', true) }}y~\TB~}  
    enableservice('AutomationServer') lu2"?y[2  
    QpbyC_:;$4  
    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 7#wdBB%  
    D',[M)  
    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: KsZd.Rf=@  
    1. 在FRED脚本编辑界面找到参考. U51C /A  
    2. 找到Matlab Automation Server Type Library '[V}]Z>-  
    3. 将名字改为MLAPP ]n _OQ)VO

    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。 HE6 kt6

    现在将脚本代码公布如下,此脚本执行如下几个步骤: U (*k:Fw  
    1. 创建Matlab服务器。 F-0|&0  
    2. 移动探测面对于前一聚焦面的位置。 F6,[!.wl  
    3. 在探测面追迹光线 anxZ|DE  
    4. 在探测面计算照度 t|XQFb@}  
    5. 使用PutWorkspaceData发送照度数据到Matlab pH!e<m  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 jr,j1K@_t  
    7. 用Matlab画出照度数据 *>"k/XUn$  
    8. 在Matlab计算照度平均值 BUhLAO  
    9. 返回数据到FRED中 St 4YNS.|
