FRED如何调用Matlab

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。 [6Nzz]yy  
4> [tjz.?k  
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: 9\NP)Vm$^  
enableservice('AutomationServer', true) QnDLSMx)  
enableservice('AutomationServer') V-9z{  
#*K!@X  
结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 /K#J63 ,  
?B,B<@='%  
在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: >za=v  
1. 在FRED脚本编辑界面找到参考. 6I\mhw!pQ  
2. 找到Matlab Automation Server Type Library \U'TL_Ql  
3. 将名字改为MLAPP ,}42]%$ G  
\A3yM{G~+  
T]J#>LBd  
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。 &@xeWB

现在将脚本代码公布如下,此脚本执行如下几个步骤: ! J@pox-t  
1. 创建Matlab服务器。 pDx}~IB  
2. 移动探测面对于前一聚焦面的位置。 /-)|dP  
3. 在探测面追迹光线 kOuQR$9s  
4. 在探测面计算照度 Th//uI+  
5. 使用PutWorkspaceData发送照度数据到Matlab Pi|oO-M  
6. 使用PutFullMatrix发送标量场数据到Matlab中 \it<]BN  
7. 用Matlab画出照度数据 6hm6h7$F1  
8. 在Matlab计算照度平均值 _.Bite^  
9. 返回数据到FRED中 /waZ9
