[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。 X,3\c:  
ZpOME@9,  
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： VPT?z  
enableservice('AutomationServer', true) =gJ{75tV3  
enableservice('AutomationServer') v.C  
f9>pMfi:@  
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。 >I~Q[

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：

1. 在FRED脚本编辑界面找到参考. $},XRo&R  
2. 找到Matlab Automation Server Type Library >M{98NH  
3. 将名字改为MLAPP !xR9I0V5

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。 rL"]m_FK

现在将脚本代码公布如下，此脚本执行如下几个步骤： 08^f|K  
1. 创建Matlab服务器。 svEe@Kt`  
2. 移动探测面对于前一聚焦面的位置。 *@#Gc%mGu  
3. 在探测面追迹光线 ~%h )G#N  
4. 在探测面计算照度 K O\HH  
5. 使用PutWorkspaceData发送照度数据到Matlab JS m7-p|E  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Qu'#~#L`  
7. 用Matlab画出照度数据 OwNM`xSa|\  
8. 在Matlab计算照度平均值

9. 返回数据到FRED中 PZJn/A1
