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。 cp h:y  
Wl}&?v&@  
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: K<>sOWZ'S  
enableservice('AutomationServer', true) )vxUT{;sH  
enableservice('AutomationServer') M9f35 :  
ZK)%l~J  
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。 j1(D]Z=\  
aM;W$1h  
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: Sf8{h|71  
1. 在FRED脚本编辑界面找到参考. Q%f|~Kl-hd  
2. 找到Matlab Automation Server Type Library 7VP32Eh[  
3. 将名字改为MLAPP VH:]@x//{  
9+pmS#>_  
0x!2ihf  
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。 x,'!eCKN

现在将脚本代码公布如下,此脚本执行如下几个步骤: Gw1@KKg  
1. 创建Matlab服务器。 YX#-nyK  
2. 移动探测面对于前一聚焦面的位置。 MuSUKBhM  
3. 在探测面追迹光线 D$x_o!JT  
4. 在探测面计算照度 dh $bfAb  
5. 使用PutWorkspaceData发送照度数据到Matlab >+[&3u  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Ot`VR&}  
7. 用Matlab画出照度数据 =lpQnj"  
8. 在Matlab计算照度平均值 )l#E}Uz  
9. 返回数据到FRED中 {*ob_oc
