[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。 f@`|2wG  
B9,39rG/7+  
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： {_!,T%>+1  
enableservice('AutomationServer', true) 1
Xi>&;],  
enableservice('AutomationServer') jOCV)V9}  
m=n79]b:N  
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。 @(c^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： Rk5#5R n  
1. 在FRED脚本编辑界面找到参考. I:t?#)wl  
2. 找到Matlab Automation Server Type Library XZN@hXc9:v  
3. 将名字改为MLAPP ktPM66`b

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。 z 8M\(<

现在将脚本代码公布如下，此脚本执行如下几个步骤： bLS10^g5  
1. 创建Matlab服务器。 jvv=  
2. 移动探测面对于前一聚焦面的位置。 >!qtue7B  
3. 在探测面追迹光线 8N)Lck2PR  
4. 在探测面计算照度 p8XvfM  
5. 使用PutWorkspaceData发送照度数据到Matlab UU(Pg{DA6  
6. 使用PutFullMatrix发送标量场数据到Matlab中 [^GBg>k  
7. 用Matlab画出照度数据 v5@4|u3ds  
8. 在Matlab计算照度平均值 eaO'|@;{~  
9. 返回数据到FRED中 I~6(>Z{
