[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。 =sa bJsgL  
xfqW~&  
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： '@ C\,E  
enableservice('AutomationServer', true) L.1pO2zPe  
enableservice('AutomationServer') f[$9k}.  
^"hsbk&Yu  
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。 b*@y/ e\u`

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： wU=@,K  
1. 在FRED脚本编辑界面找到参考. q9mYhT/Im  
2. 找到Matlab Automation Server Type Library km+}./@  
3. 将名字改为MLAPP vJE>H4qPmD

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。 tE>hj:p

现在将脚本代码公布如下，此脚本执行如下几个步骤： <u9U%Vsi  
1. 创建Matlab服务器。

2. 移动探测面对于前一聚焦面的位置。 E%E3h1Ua  
3. 在探测面追迹光线 k2S6 SB  
4. 在探测面计算照度 *=O~TY<](  
5. 使用PutWorkspaceData发送照度数据到Matlab 3"

6. 使用PutFullMatrix发送标量场数据到Matlab中 ZZXQCP6]  
7. 用Matlab画出照度数据 h r!Htew4  
8. 在Matlab计算照度平均值 L8zY?v(bG  
9. 返回数据到FRED中 ]/y&5X
