    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。 zO7lsx2 =  
    f0HV*%8  
    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: _dJVnC1 !  
    enableservice('AutomationServer', true) ->RF`SQu  
    enableservice('AutomationServer') |P[D2R}  
    l{D,O?`Av  
    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 /4f 5s#hR  
    NL>[8#  
    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: sEgeS9a{  
    1. 在FRED脚本编辑界面找到参考. "\R@l Ux.Y  
    2. 找到Matlab Automation Server Type Library =km-` }I,  
    3. 将名字改为MLAPP I1}{~@

    EnsNO_"e|  
    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。 ? A^3.`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: hjm .Ath  
    1. 创建Matlab服务器。 x:&L?eOT  
    2. 移动探测面对于前一聚焦面的位置。 F%ylR^H>  
    3. 在探测面追迹光线 l5N\> q  
    4. 在探测面计算照度 ck4T#g;=  
    5. 使用PutWorkspaceData发送照度数据到Matlab Sv^'CpQ  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 1rvf\[  
    7. 用Matlab画出照度数据 51FK~ 5  
    8. 在Matlab计算照度平均值 =+sIX3  
    9. 返回数据到FRED中 ^F{)&#4
