[推荐]FRED案例-FRED如何调用Matlab [复制链接]

xaoaZ3Ko  
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。 n~8-+$6OR  
)qn =  
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： <gZC78}E  
enableservice('AutomationServer', true) Fng":28o  
    enableservice('AutomationServer') I:]s/r7  
b&*^\hY9b  
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。 X z2IAiAs'

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： :&2RV_$>=  
1. 在FRED脚本编辑界面找到参考. e l'^9K  
2. 找到Matlab Automation Server Type Library VaZS_qGe:  
    3. 将名字改为MLAPP 6@wnF>'/\  
     H 
}uT'  
     [uc;M6o}?  
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。 gEO#-tMjOQ

现在将脚本代码公布如下，此脚本执行如下几个步骤： |I^\|5  
1. 创建Matlab服务器。 dB<BEe\$g.  
2. 移动探测面对于前一聚焦面的位置。 n4>
 
3. 在探测面追迹光线 6b-d#H/1Y  
4. 在探测面计算照度 \&2GLBKpe  
5. 使用PutWorkspaceData发送照度数据到Matlab 5|r3i \  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 <Sm=,Sw  
7. 用Matlab画出照度数据 C(}9  
8. 在Matlab计算照度平均值 ^^jF*)DT@  
9. 返回数据到FRED中 H3QAIsGS
