[推荐]FRED案例-FRED如何调用Matlab [复制链接]

Mu2`ODe]  
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。 g_q<ze  
@Y-TOCadT  
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： mQr0sI,o]  
enableservice('AutomationServer', true) fu]N""~  
    enableservice('AutomationServer') >qh?L#Fk  
Hg+ F^2<y  
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。 }l;Lxb2`

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： K)N0,Qwu  
1. 在FRED脚本编辑界面找到参考. u #~;&D*q  
2. 找到Matlab Automation Server Type Library wC` R>)  
    3. 将名字改为MLAPP &&7r+.Y

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。 |/T43ADW

现在将脚本代码公布如下，此脚本执行如下几个步骤： n:4uA`Vg  
1. 创建Matlab服务器。 v(O=IUa  
2. 移动探测面对于前一聚焦面的位置。 8l>CR#%@C  
3. 在探测面追迹光线 4["&O=:d  
4. 在探测面计算照度 Vmi{X b]<  
5. 使用PutWorkspaceData发送照度数据到Matlab X?o( b/F-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 OYmi?y\  
7. 用Matlab画出照度数据 VQxpN 1  
8. 在Matlab计算照度平均值 Jpj!rXTX*  
9. 返回数据到FRED中  +sZUJ
