    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。 O T.*pk+<)  
    yw];P o,  
    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: Ym3\pRFiD  
    enableservice('AutomationServer', true) 9$2/MT't  
    enableservice('AutomationServer') CHe>OreiS  
    ggJO:$?$L  
    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 ^R:cd8+?%

    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: u\C lP#  
    1. 在FRED脚本编辑界面找到参考. >=[(^l  
    2. 找到Matlab Automation Server Type Library w!fE;H8w6  
    3. 将名字改为MLAPP dKdj`wB

    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。 ,7<f9 EVY

    1. 创建Matlab服务器。 y3fGWa*7e  
    2. 移动探测面对于前一聚焦面的位置。 w@{=nD4p  
    3. 在探测面追迹光线 |UX(+; n  
    4. 在探测面计算照度 G K7![p  
    5. 使用PutWorkspaceData发送照度数据到Matlab Mnscb  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *s:(jDlv  
    7. 用Matlab画出照度数据 "1%5,  
    8. 在Matlab计算照度平均值 ZzSz%z_sE
