[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。 oB$c-!&  
tu:W1?  
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： h3rVa6cxM  
enableservice('AutomationServer', true) k~XDwmt;  
enableservice('AutomationServer') H
DYWDp  
fda)t1u\8  
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。 ?D_^8
\R  
Y.b?.)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： zhgvqg-  
1. 在FRED脚本编辑界面找到参考. H{4_,2h=m  
2. 找到Matlab Automation Server Type Library FI"KJk'  
3. 将名字改为MLAPP <%N*IE"q  
p|>m 2(|  
W+I""I*mV  
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。 ~5>k_\G8

现在将脚本代码公布如下，此脚本执行如下几个步骤： RqKkB8g  
1. 创建Matlab服务器。 ~5o2jTNy`p  
2. 移动探测面对于前一聚焦面的位置。 Zd}12HFq  
3. 在探测面追迹光线 {8"Uxj_6V  
4. 在探测面计算照度 W1JvLU5L*r  
5. 使用PutWorkspaceData发送照度数据到Matlab "0Z5cQjg  
6. 使用PutFullMatrix发送标量场数据到Matlab中 H6hhU'Kxf8  
7. 用Matlab画出照度数据 Oe21noL  
8. 在Matlab计算照度平均值 wUfm)Q#  
9. 返回数据到FRED中 /*(&Dmt>
