[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。 QjG/H0*mP  
NA'45}fQ  
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： ?A_+G 5  
enableservice('AutomationServer', true) _KxR~
k^  
enableservice('AutomationServer') &GJVFr~z  
VNIl%9:-l  
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。 XM*5I4V

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： |9IOZ

1. 在FRED脚本编辑界面找到参考.

2. 找到Matlab Automation Server Type Library Ut;4`>T  
3. 将名字改为MLAPP JJSE@$",\

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。 w4\ 3*

现在将脚本代码公布如下，此脚本执行如下几个步骤： n5.sx|bI?  
1. 创建Matlab服务器。 sCrP+K0D  
2. 移动探测面对于前一聚焦面的位置。 =mZYBm,IQ  
3. 在探测面追迹光线 :Hm'o}  
4. 在探测面计算照度 6Q]c}  
5. 使用PutWorkspaceData发送照度数据到Matlab Pvi2j&W84  
6. 使用PutFullMatrix发送标量场数据到Matlab中 4* >j:1  
7. 用Matlab画出照度数据 83/m^^F{]  
8. 在Matlab计算照度平均值 _
