[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。 iQiXwEAi[  
Q[T)jo,j%  
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： n(Um/  
enableservice('AutomationServer', true) T.WN9=N  
enableservice('AutomationServer') ra
MtTL+  
,L\KS^>  
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。 $?OQtz@

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： )[E7\pc  
1. 在FRED脚本编辑界面找到参考. W$gjcsv  
2. 找到Matlab Automation Server Type Library R0q|{5S  
3. 将名字改为MLAPP +}f}!h;

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。  Ozsvsa

现在将脚本代码公布如下，此脚本执行如下几个步骤： pA\"Xe&  
1. 创建Matlab服务器。 w:~

2. 移动探测面对于前一聚焦面的位置。 WjvgDNk  
3. 在探测面追迹光线 LS<*5HWX  
4. 在探测面计算照度 Zo Ra^o  
5. 使用PutWorkspaceData发送照度数据到Matlab 8;3I:z&muQ  
6. 使用PutFullMatrix发送标量场数据到Matlab中 _6aI>b#yL  
7. 用Matlab画出照度数据

8. 在Matlab计算照度平均值 [E qZj/  
9. 返回数据到FRED中 ]];LA!
