[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。 KCqqJ}G  
"dCzWFet  
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： aC\4}i<  
enableservice('AutomationServer', true) z1j|E :  
enableservice('AutomationServer') 3:`XG2'  
TipHV;|e  
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。

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： -Zy)5NB-tZ  
1. 在FRED脚本编辑界面找到参考. Jq1 n0O  
2. 找到Matlab Automation Server Type Library @EZ>f5IO+  
3. 将名字改为MLAPP d<T%`:s<  
`iYc<N`

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。 3E|;r _; 8

现在将脚本代码公布如下，此脚本执行如下几个步骤： !#}>Hv^N  
1. 创建Matlab服务器。 >4)g4~'n!  
2. 移动探测面对于前一聚焦面的位置。 L#j/0IHD  
3. 在探测面追迹光线 L3c*LL  
4. 在探测面计算照度 z,Xk\@  
5. 使用PutWorkspaceData发送照度数据到Matlab i^g~~h F  
6. 使用PutFullMatrix发送标量场数据到Matlab中 /bcY6b=:  
7. 用Matlab画出照度数据 [b1hC ~I;  
8. 在Matlab计算照度平均值 htHv&  
9. 返回数据到FRED中 ,U=E[X=
