[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-79

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： {~V_6wY g  
enableservice('AutomationServer', true) PI)uBA;  
enableservice('AutomationServer') C9j5Pd5q1L  
\,G19o}`Es  
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。 +WvW#wpH

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： s5ILl wr  
1. 在FRED脚本编辑界面找到参考. 3V/f-l]X/  
2. 找到Matlab Automation Server Type Library "R[6Q ^vw  
3. 将名字改为MLAPP Bm;@}Ly=G

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。 /4 .]L~

现在将脚本代码公布如下，此脚本执行如下几个步骤： >+S* Wtm5  
1. 创建Matlab服务器。 ;zo?o t/  
2. 移动探测面对于前一聚焦面的位置。 2vW@d[<J  
3. 在探测面追迹光线 nVk]Qe  
4. 在探测面计算照度 ; zfBe%Uf  
5. 使用PutWorkspaceData发送照度数据到Matlab R[2h!.O8  
6. 使用PutFullMatrix发送标量场数据到Matlab中 &_Z8:5e  
7. 用Matlab画出照度数据 4OdK@+-8U  
8. 在Matlab计算照度平均值 9|hPl-. .W  
9. 返回数据到FRED中 e(k$k>?
