    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。 l;I)$=={=  
    \@6nRs8b|N  
    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: 3%<Uq%pJ  
    enableservice('AutomationServer', true) 6]%79?'A  
    enableservice('AutomationServer') B*+3A!{s  
    l@8UL</W  
    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 ydCVG,"  
    @Fp-6J  
    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: A Z7  
    1. 在FRED脚本编辑界面找到参考. +`_I !  
    2. 找到Matlab Automation Server Type Library ,7m Rb-*p  
    3. 将名字改为MLAPP m]yt6b4  
    J Cu3,O!q  
    I<q=lK  
    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。 x<'(b7{U0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: fI2/v<[  
    1. 创建Matlab服务器。 fX,L;Se"  
    2. 移动探测面对于前一聚焦面的位置。 @_tQ:U,v  
    3. 在探测面追迹光线 #Y3:~dmJ-  
    4. 在探测面计算照度 J`T1 88  
    5. 使用PutWorkspaceData发送照度数据到Matlab ,O@x v  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 /YbyMj*  
    7. 用Matlab画出照度数据 qW57h8M  
    8. 在Matlab计算照度平均值 ;- D1n  
    9. 返回数据到FRED中 +?[ ,y
