[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。 lnUy?0(  
Kxn=iv^Ir  
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： }q
g&2M%\  
enableservice('AutomationServer', true) P nDZi  
enableservice('AutomationServer') +ZO*~.zZ  
sa])^mkq(  
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。 ,'}ZcN2)

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： TY}?>t+  
1. 在FRED脚本编辑界面找到参考. CJ>=odK[  
2. 找到Matlab Automation Server Type Library %

3. 将名字改为MLAPP 9:WKG'E8a

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。 _4w%U[GT,

现在将脚本代码公布如下，此脚本执行如下几个步骤： -_dgd:or  
1. 创建Matlab服务器。 78"W ~`8  
2. 移动探测面对于前一聚焦面的位置。 70Am]L&M  
3. 在探测面追迹光线 pD9c%P  
4. 在探测面计算照度 nK[$ID  
5. 使用PutWorkspaceData发送照度数据到Matlab Y;WrfO$J  
6. 使用PutFullMatrix发送标量场数据到Matlab中 uB
XI*51{  
7. 用Matlab画出照度数据 wKN9HT  
8. 在Matlab计算照度平均值 1vr/|RWW  
9. 返回数据到FRED中 A{k@V!A%
