[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。 qAAX;N  
]^Qn  
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： +b.g$CRr  
enableservice('AutomationServer', true) NL!u<6y  
enableservice('AutomationServer') 
d9B]fi}  
8VeQ-#7M/  
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。 +aJ>rR

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： brW :C?}  
1. 在FRED脚本编辑界面找到参考. 19HM])Zw\  
2. 找到Matlab Automation Server Type Library 2[Z,J%:0  
3. 将名字改为MLAPP Hw7;;HK 7

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。 uehDIl0\[b

现在将脚本代码公布如下，此脚本执行如下几个步骤： U*i{5/$  
1. 创建Matlab服务器。 R$

2. 移动探测面对于前一聚焦面的位置。 C"!gZ8*\!9  
3. 在探测面追迹光线 N):tOD@B  
4. 在探测面计算照度 &^#VN%{  
5. 使用PutWorkspaceData发送照度数据到Matlab {_`^R>"\&w  
6. 使用PutFullMatrix发送标量场数据到Matlab中 4?ICy/,U-  
7. 用Matlab画出照度数据 bL'aB{s  
8. 在Matlab计算照度平均值 S'4(0j  
9. 返回数据到FRED中 Jz7!4mu
