[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。 rocB"0  
Q+d.%qhc  
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： 8pPC 9ew\=  
enableservice('AutomationServer', true) X&(ERY,h  
enableservice('AutomationServer') z
]c,}Q  
/S]:dDY9K  
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。 hDljY!P>p

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： \- =^]]b=  
1. 在FRED脚本编辑界面找到参考. *`ZB+ \*  
2. 找到Matlab Automation Server Type Library 'B3Wza.  
3. 将名字改为MLAPP S,9NUt

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。 +YkW[a\4

现在将脚本代码公布如下，此脚本执行如下几个步骤： oWp}O?  
1. 创建Matlab服务器。 m_m8c8{

2. 移动探测面对于前一聚焦面的位置。 rFmKmV  
3. 在探测面追迹光线 %j'G.*TD  
4. 在探测面计算照度 =#i4MXRZ{  
5. 使用PutWorkspaceData发送照度数据到Matlab X,TTM,1w  
6. 使用PutFullMatrix发送标量场数据到Matlab中 =.36y9Mfo  
7. 用Matlab画出照度数据 K`QOU-M@}  
8. 在Matlab计算照度平均值 lt{lpH  
9. 返回数据到FRED中 Y=vVxVI\
