[技术]FRED如何调用Matlab [复制链接]

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。 cXG$zwS\  
|GnqfD  
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： b0!ZA/YC-  
enableservice('AutomationServer', true) 3eJ"7sftW
 
enableservice('AutomationServer') 4WZ"8  
?9m@ S#@  
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。 AWn$od`#s

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： #a=~a=c(^  
1. 在FRED脚本编辑界面找到参考.  N2Q%/}+,  
2. 找到Matlab Automation Server Type Library f%5 s8)  
3. 将名字改为MLAPP ^h\Y.

 /DN!"  
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。 x4nmDEpa

现在将脚本代码公布如下，此脚本执行如下几个步骤： h!h<!xaclW  
1. 创建Matlab服务器。 m*Q*{M_e  
2. 移动探测面对于前一聚焦面的位置。 /5 6sPl 7}  
3. 在探测面追迹光线 %_%/ym  
4. 在探测面计算照度 76rRF   
5. 使用PutWorkspaceData发送照度数据到Matlab }qn@8}  
6. 使用PutFullMatrix发送标量场数据到Matlab中 'SE?IE{  
7. 用Matlab画出照度数据 52>,JHq  
8. 在Matlab计算照度平均值

9. 返回数据到FRED中 ej&ZE n
