[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。 3+r8yiY  
[y$sJF7;I  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： G |vG5$Nf  
enableservice('AutomationServer', true) L-(.v*  
enableservice('AutomationServer') "npLl]XM  
C9FQo7  
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。 eI*o9k$Qs

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： 'x!

1. 在FRED脚本编辑界面找到参考. k M' :.QT  
2. 找到Matlab Automation Server Type Library D.R 7#^.  
3. 将名字改为MLAPP V$fv

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。 uvf}7

3. 在探测面追迹光线 K0O&-v0"1  
4. 在探测面计算照度 Ljjuf=]

6. 使用PutFullMatrix发送标量场数据到Matlab中 d%:
