    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。 !.%*Tp#k#  
    xj33g6S  
    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: ommW  
    enableservice('AutomationServer', true) w*"Ii%iA<  
    enableservice('AutomationServer') t ^>07#z  
    BO}IN#  
    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 DNj<:Pdd)  
    CD`6R.  
    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: /Gnt.%y&  
    1. 在FRED脚本编辑界面找到参考. k6DJ(.n'%a  
    2. 找到Matlab Automation Server Type Library _!|$i  
    3. 将名字改为MLAPP {R(/Usg!=  
    i.^UkN{  
    ?lqqu#;8  
    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。 O:+y/c

    现在将脚本代码公布如下,此脚本执行如下几个步骤: b"@-9ke5I  
    1. 创建Matlab服务器。 9FC_B+7  
    2. 移动探测面对于前一聚焦面的位置。 _ \+0e:Ae  
    3. 在探测面追迹光线 #2\M(5d  
    4. 在探测面计算照度 `r&Ui%fk;0  
    5. 使用PutWorkspaceData发送照度数据到Matlab fFC9:9<  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 BGfwgI.m  
    7. 用Matlab画出照度数据 ZH=Bm^  
    8. 在Matlab计算照度平均值 - A}$5/  
    9. 返回数据到FRED中 6}@T^?
