    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。 MpV6Vbp  
    ;rj=hc  
    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: l|[8'*]r!  
    enableservice('AutomationServer', true) OudD1( )W  
    enableservice('AutomationServer') cN>z`x l  
    7x%0 ^~/n  
    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 ]byj[Gd  
    ^%v<I"<Uq5  
    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: 3huT T"G  
    1. 在FRED脚本编辑界面找到参考. jF'azlT  
    2. 找到Matlab Automation Server Type Library 6' M"-9?G  
    3. 将名字改为MLAPP eKL)jzC:

    Q-[^!RAK?  
    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。 c{Ax{-'R

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Sdc;jK 9d!  
    1. 创建Matlab服务器。 4=H/-v'&  
    2. 移动探测面对于前一聚焦面的位置。 W`C&$v#  
    3. 在探测面追迹光线 >mT< AQ  
    4. 在探测面计算照度 7CGKm8T  
    5. 使用PutWorkspaceData发送照度数据到Matlab K/ q:aMq  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 x@I@7Pvo3  
    7. 用Matlab画出照度数据 \^wI9g~0  
    8. 在Matlab计算照度平均值 Ah_'.r1<P9  
    9. 返回数据到FRED中 >9f-zv(n
