[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。 ,|QU] E @  
}Y$VB%&Hy  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： T@>63  
enableservice('AutomationServer', true) j>g9\i0O1  
enableservice('AutomationServer') " xxXZGUp  
|>[X<>m  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 a~F u  
!z.^(Tj  
在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： =~;zVP   
1. 在FRED脚本编辑界面找到参考. mlmnkgl ]  
2. 找到Matlab Automation Server Type Library 2q$X>ImI$  
3. 将名字改为MLAPP 6z`8cI+LRw

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。 3_@G{O)e

现在将脚本代码公布如下，此脚本执行如下几个步骤： 0YHYxn  
1. 创建Matlab服务器。 ~JT lPU'  
2. 移动探测面对于前一聚焦面的位置。 V?o&])?[  
3. 在探测面追迹光线 5Wj5IS/  
4. 在探测面计算照度 /.f!  
5. 使用PutWorkspaceData发送照度数据到Matlab \J\vp0[nO}  
6. 使用PutFullMatrix发送标量场数据到Matlab中 H.f9d.<W%  
7. 用Matlab画出照度数据 M`q#,Y?3^I  
8. 在Matlab计算照度平均值 6l=M;B7:i  
9. 返回数据到FRED中 OHQ3+WJ
