[推荐]FRED案例-FRED如何调用Matlab [复制链接]

\1 &,|\E#  
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。 WoRZW%  
nl,uuc*;  
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： fG(SNNl+D  
enableservice('AutomationServer', true) -FQ 'agf@&  
    enableservice('AutomationServer') V0XvJ  
)fSOi||C  
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。 Nf"r4%M<6  
<r`2)[7N  
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： 8j %Tf;  
1. 在FRED脚本编辑界面找到参考. I\JGs@I   
2. 找到Matlab Automation Server Type Library =k0_eX0  
    3. 将名字改为MLAPP M|`U"vO

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。 Q_X.rUL0w

现在将脚本代码公布如下，此脚本执行如下几个步骤： Om@C X<(9C  
1. 创建Matlab服务器。 thM4vq  
2. 移动探测面对于前一聚焦面的位置。 R1GEh&U{  
3. 在探测面追迹光线 }m;,Q9:+m^  
4. 在探测面计算照度 T7u%^xm  
5. 使用PutWorkspaceData发送照度数据到Matlab t+iHQfuP9A  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 <drODjB  
7. 用Matlab画出照度数据 B%76rEpvW;  
8. 在Matlab计算照度平均值 ^R Fp8w(  
9. 返回数据到FRED中 sCk?
