    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。 SX?$H~A  
    1$!RKqT  
    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: {DXZ}7w:v  
    enableservice('AutomationServer', true) B[0,\>  
    enableservice('AutomationServer') wx"6",M  
    Er/5 ,  
    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 = C'e1=]  
    I_6` Z 0  
    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: -g[*wN8  
    1. 在FRED脚本编辑界面找到参考. /o1)ZC$  
    2. 找到Matlab Automation Server Type Library 4h_4jqf=pU  
    3. 将名字改为MLAPP :5cu,&<Gv  
    d Xo'#.

    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。 @aD~YtL"n

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ^qus `6  
    1. 创建Matlab服务器。 h%w\O Z7  
    2. 移动探测面对于前一聚焦面的位置。 ma-Y'  
    3. 在探测面追迹光线 ,^IZ[D>u)  
    4. 在探测面计算照度 rLw[y$2  
    5. 使用PutWorkspaceData发送照度数据到Matlab yxP?O@(  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 dYqDL<se/I  
    7. 用Matlab画出照度数据 x&fCe{5  
    8. 在Matlab计算照度平均值 SQKY;p  
    9. 返回数据到FRED中 -L'K
