[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。 TJ8E"t*)
 
 $!@\  
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： ?(6mVyIe  
enableservice('AutomationServer', true) 3uu~p!2  
enableservice('AutomationServer') owpWz6k7  
Ty(@+M~-  
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。 L)QE`24

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： V D?*h  
1. 在FRED脚本编辑界面找到参考. ?|{XZQ~  
2. 找到Matlab Automation Server Type Library <|Yj%f  
3. 将名字改为MLAPP P>Euq'ajX

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。 j9+I0>#X

现在将脚本代码公布如下，此脚本执行如下几个步骤： #%@*p,xh  
1. 创建Matlab服务器。 DHC+C4  
2. 移动探测面对于前一聚焦面的位置。 C`jM0Q  
3. 在探测面追迹光线 iZ3W"Vd`b  
4. 在探测面计算照度 {%v-(  
5. 使用PutWorkspaceData发送照度数据到Matlab 5l-mW0,MK  
6. 使用PutFullMatrix发送标量场数据到Matlab中 GV6K/T:  
7. 用Matlab画出照度数据 pg+[y<B  
8. 在Matlab计算照度平均值  >YtdA  
9. 返回数据到FRED中 OX:O^ (-r,
