[技术]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。 nxyjL)!)0  
i5 L:L  
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： *bCi2mbm@  
enableservice('AutomationServer', true) c{
mK
ra  
enableservice('AutomationServer') llHc=&y#  
\-Iny=$  
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。 6wb^*dD92

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： I%}L@fZ  
1. 在FRED脚本编辑界面找到参考. Vl{~@G,@  
2. 找到Matlab Automation Server Type Library @PPR$4  
3. 将名字改为MLAPP 7_Ba3+9jpa  
6_R\l@a  
`E} p77  
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。 (px*R~}

现在将脚本代码公布如下，此脚本执行如下几个步骤： tS\=<T  
1. 创建Matlab服务器。 Ky[bX  
2. 移动探测面对于前一聚焦面的位置。 5Noe/6  
3. 在探测面追迹光线 /x  
4. 在探测面计算照度 3y

5. 使用PutWorkspaceData发送照度数据到Matlab 45x,|h[F{5  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ;".z[l*  
7. 用Matlab画出照度数据 Qm.z@DwFM{  
8. 在Matlab计算照度平均值 8To7c  
9. 返回数据到FRED中 :O9P(X*
