[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。 C{AVV<
  
X/Umfci  
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： r/E'#5 Q  
enableservice('AutomationServer', true) F*Lm=^:  
enableservice('AutomationServer') Dg(882#_  
#;,dk(URo  
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。 J<J_yRg2

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： P?D;BAP2  
1. 在FRED脚本编辑界面找到参考. 5R"My^G  
2. 找到Matlab Automation Server Type Library e lj

3. 将名字改为MLAPP KtH-QQDluj

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。 4E\Jk5co,

现在将脚本代码公布如下，此脚本执行如下几个步骤： \H <k  
1. 创建Matlab服务器。 cZ>h[XX[  
2. 移动探测面对于前一聚焦面的位置。 DLMM1 A  
3. 在探测面追迹光线 5`];[M9  
4. 在探测面计算照度 lU6?p")F1  
5. 使用PutWorkspaceData发送照度数据到Matlab Wc]L4

6. 使用PutFullMatrix发送标量场数据到Matlab中  n *Y+y  
7. 用Matlab画出照度数据 |-kU]NJFR  
8. 在Matlab计算照度平均值 Dxj&9Ra  
9. 返回数据到FRED中 ?8dd^iX/
