FRED案例-FRED如何调用Matlab

uQ^hV%|"  
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。 D:)~%wu Lt  
<p/MyqZf  
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: #<]Iz'\`  
enableservice('AutomationServer', true) :$2Yg[Zc3  
    enableservice('AutomationServer') s-%J 5_d f  
PT05DH  
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。 B\/7^{i5  
cd+^=esSO  
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: k,lqT>C  
1. 在FRED脚本编辑界面找到参考. -O%[!&`  
2. 找到Matlab Automation Server Type Library iJ4 <f->t  
    3. 将名字改为MLAPP i pwW%"6  
     =Sa~\k+  
     z'*ml ?  
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。 2m_H*1 HJ

现在将脚本代码公布如下,此脚本执行如下几个步骤: %z2oDAjX  
1. 创建Matlab服务器。 6&mWIk^VC  
2. 移动探测面对于前一聚焦面的位置。 0Gx*'B=  
3. 在探测面追迹光线 NZfd_? 3  
4. 在探测面计算照度 M/l95fp   
5. 使用PutWorkspaceData发送照度数据到Matlab FCAJavOGH  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 /cYk+c  
7. 用Matlab画出照度数据 pagC(F  
8. 在Matlab计算照度平均值 @ct#s:t  
9. 返回数据到FRED中 F  "!`X#
