[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。 9Q+'n$s0^  
H"dJ6  
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： 
>\Ww;1yV  
enableservice('AutomationServer', true) ikSt"}/hd  
enableservice('AutomationServer') ]@Uq=?%  
A'&K/)Z  
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。 HEM9E&rL

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： E`uY1B[c  
1. 在FRED脚本编辑界面找到参考. hK,Sf ;5V  
2. 找到Matlab Automation Server Type Library _c_[C*T]  
3. 将名字改为MLAPP _`:1M2=

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。 AGYc |;

现在将脚本代码公布如下，此脚本执行如下几个步骤： N<-gI9_  
1. 创建Matlab服务器。 TmV,&['mg  
2. 移动探测面对于前一聚焦面的位置。 [CXrSST")E  
3. 在探测面追迹光线 8Hn|cf0  
4. 在探测面计算照度 j4uvS!  
5. 使用PutWorkspaceData发送照度数据到Matlab ?}U(3  
6. 使用PutFullMatrix发送标量场数据到Matlab中 %*0^0wz  
7. 用Matlab画出照度数据 h*u  
8. 在Matlab计算照度平均值 7OJ'){R$  
9. 返回数据到FRED中 70Wggty
