[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。 j 7O!uUQQ  
o2]Np~`g,  
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!+v*+R+V  
enableservice('AutomationServer', true) K@osD7-  
enableservice('AutomationServer') _XrlCLp: d  
6BQq|:U  
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。 33hP/p%

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： w`#9Re  
1. 在FRED脚本编辑界面找到参考. k4:=y9`R}$  
2. 找到Matlab Automation Server Type Library YVz,P_\(m  
3. 将名字改为MLAPP ^tjM1uaZ5(

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。 ;\/RgN

现在将脚本代码公布如下，此脚本执行如下几个步骤： 1x+w|h  
1. 创建Matlab服务器。 y,<\d/YY@  
2. 移动探测面对于前一聚焦面的位置。 *;T HD>  
3. 在探测面追迹光线 akgvV~

4. 在探测面计算照度 N{!@M_C^%R  
5. 使用PutWorkspaceData发送照度数据到Matlab 8}Maj  
6. 使用PutFullMatrix发送标量场数据到Matlab中 <2I<Z'B,e  
7. 用Matlab画出照度数据 reoCyP\!!  
8. 在Matlab计算照度平均值 }\ya6Gi8  
9. 返回数据到FRED中 w~e$ul(IQM
