[分享]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。 s^YTI\L \  
aT:AxYn8  
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： uO@3vY',n  
enableservice('AutomationServer', true) Secq^#]8  
enableservice('AutomationServer') ^qGA!_

KV}){  
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。 M*|VLOo=v  
1i/::4=  
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： TT2cOw  
1. 在FRED脚本编辑界面找到参考. J4v0O="  
2. 找到Matlab Automation Server Type Library $.Q>M]xH  
3. 将名字改为MLAPP WAB0e~e:|Q

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。 =v4r M0m,

现在将脚本代码公布如下，此脚本执行如下几个步骤： {(z(NgXG/  
1. 创建Matlab服务器。 S2&9#6  
2. 移动探测面对于前一聚焦面的位置。 >*= =wlOB  
3. 在探测面追迹光线 +rsl( 08FY  
4. 在探测面计算照度 {[,Wn:  
5. 使用PutWorkspaceData发送照度数据到Matlab 8VuZ,!WH#  
6. 使用PutFullMatrix发送标量场数据到Matlab中 o"#TZB+k
 
7. 用Matlab画出照度数据 ZEj!jWP2m  
8. 在Matlab计算照度平均值 8pk#sJ51  
9. 返回数据到FRED中 8wX+ZL:9
