    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。 ~5aE2w0K   
    :R6Q=g=  
    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: >l1 r,/\\  
    enableservice('AutomationServer', true) =]>%t]  
    enableservice('AutomationServer') }p3b#fAr  
    M?&zY "c  
    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 xF8S*,#,*  
    ZW4aY}~)$  
    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: D,;\F,p  
    1. 在FRED脚本编辑界面找到参考. m2bDHQ+  
    2. 找到Matlab Automation Server Type Library L4' [XcY  
    3. 将名字改为MLAPP yyl#{Nl@t  
    'imU `zeo  
    PXYE;*d(  
    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~"K|' G

    现在将脚本代码公布如下,此脚本执行如下几个步骤: [~%`N*G  
    1. 创建Matlab服务器。 ] f 7#N  
    2. 移动探测面对于前一聚焦面的位置。 8e:vWgQpL  
    3. 在探测面追迹光线 5~VosUp e7  
    4. 在探测面计算照度 z/|BH^Vw  
    5. 使用PutWorkspaceData发送照度数据到Matlab nfE@R."A  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 SG]K   
    7. 用Matlab画出照度数据 <4X?EYaTq  
    8. 在Matlab计算照度平均值 M}FWBs'*|  
    9. 返回数据到FRED中 vgG}d8MW37
