[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。 Q%W>m0%  
S59^$  
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： vr4{|5M  
enableservice('AutomationServer', true) d^8n  
enableservice('AutomationServer') hjz`0AS  
<B!DwMk;.  
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。 piFZu/~Gq\

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： ;Kh?iqn^  
1. 在FRED脚本编辑界面找到参考. Y+eDE:4  
2. 找到Matlab Automation Server Type Library ]U&<y8Q_6  
3. 将名字改为MLAPP <8^ws90Y

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。 EUW>8kw0

现在将脚本代码公布如下，此脚本执行如下几个步骤： <j1r6.E)  
1. 创建Matlab服务器。 i,rX.K}X  
2. 移动探测面对于前一聚焦面的位置。 R&Ss ET.  
3. 在探测面追迹光线 uSv]1m_-]  
4. 在探测面计算照度 c4.2o<(Xt  
5. 使用PutWorkspaceData发送照度数据到Matlab Kw(S<~9-@  
6. 使用PutFullMatrix发送标量场数据到Matlab中 GK[Hs1/  
7. 用Matlab画出照度数据 :q~5Xw/  
8. 在Matlab计算照度平均值 UG3}|\.u  
9. 返回数据到FRED中 hFnUw26P
