[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。 1}~ZsrF

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： 0j2mTF(C  
enableservice('AutomationServer', true) L]q%;u]8!  
enableservice('AutomationServer') )"J1ET,z  
?DE{4Ti/[  
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。 ]:}7-;$V

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： IEe;ygL#  
1. 在FRED脚本编辑界面找到参考. q|

2. 找到Matlab Automation Server Type Library uR.`8s|  
3. 将名字改为MLAPP y+ 4#Iy

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。 ]GDjR'[z

现在将脚本代码公布如下，此脚本执行如下几个步骤： 1.5R`vKn]  
1. 创建Matlab服务器。 4n*`%V  
2. 移动探测面对于前一聚焦面的位置。 T%A"E,#  
3. 在探测面追迹光线 <B'PB"R3y  
4. 在探测面计算照度 o7^0Lo5Z?  
5. 使用PutWorkspaceData发送照度数据到Matlab iI;np+uYk  
6. 使用PutFullMatrix发送标量场数据到Matlab中 +1r><do;  
7. 用Matlab画出照度数据 (+}44Ldt  
8. 在Matlab计算照度平均值 4]ko  
9. 返回数据到FRED中 2Z?l,M~
