[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。 qIIJ4n  
,<-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： D^Jk@<*  
enableservice('AutomationServer', true) ^r6!l.  
enableservice('AutomationServer') En{`@JsM  
TaE~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。 vS\Nd1~?

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： +N`ua  
1. 在FRED脚本编辑界面找到参考. ziPR>iz-  
2. 找到Matlab Automation Server Type Library $5x ,6[&  
3. 将名字改为MLAPP UT0){%2@

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。 7x);x/#8Z

1. 创建Matlab服务器。 ~5FW[_  
2. 移动探测面对于前一聚焦面的位置。 tW WW

3. 在探测面追迹光线 hj'(*ND7z  
4. 在探测面计算照度 HY)-/  
5. 使用PutWorkspaceData发送照度数据到Matlab ;X*cCb`h  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ~t9tnLc$  
7. 用Matlab画出照度数据 J'$>Gk]  
8. 在Matlab计算照度平均值 <-D/
