[技术]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。 O@,i1ha%  
0wvU?z%WK  
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： >\bPZf)tJ)  
enableservice('AutomationServer', true) 
g i4  
enableservice('AutomationServer') yN:>!SQ  
JQT4N[rEE  
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。 q/'MS[C

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： i./Y w
 
1. 在FRED脚本编辑界面找到参考. vKkf2 7  
2. 找到Matlab Automation Server Type Library B;c=eMw  
3. 将名字改为MLAPP X[{\3Av

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。 a71}y;W

1. 创建Matlab服务器。 \S5V}!_  
2. 移动探测面对于前一聚焦面的位置。 >I:9'"`  
3. 在探测面追迹光线 ] - h|]  
4. 在探测面计算照度 6\mC$:F  
5. 使用PutWorkspaceData发送照度数据到Matlab skSNzF7'  
6. 使用PutFullMatrix发送标量场数据到Matlab中 /0!$p[cjm  
7. 用Matlab画出照度数据 U%Ol^xl  
8. 在Matlab计算照度平均值 )#mW7m9M#  
9. 返回数据到FRED中 N$*>suQ,
