[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。 LyXABQ]  
w@f_TG"Vt  
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： m7mC 7x  
enableservice('AutomationServer', true) 7 ~ Bo*UM  
enableservice('AutomationServer') L'h'm{i  
 6Ue6b$xE  
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 C[$<7Mi|;

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： *JOv  
1. 在FRED脚本编辑界面找到参考. g(;ejKSR  
2. 找到Matlab Automation Server Type Library IPE

3. 将名字改为MLAPP mKq9mA"(E  
DFjkp;`1  
K<_H`k*x
 
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。 @49^WY

现在将脚本代码公布如下，此脚本执行如下几个步骤： p|bpE F=U  
1. 创建Matlab服务器。 CGg6nCB  
2. 移动探测面对于前一聚焦面的位置。 )5V1HWjU  
3. 在探测面追迹光线 Cw^)}23R  
4. 在探测面计算照度 d ly 0874  
5. 使用PutWorkspaceData发送照度数据到Matlab AU$5"kBE  
6. 使用PutFullMatrix发送标量场数据到Matlab中 J<zg 'Jk^  
7. 用Matlab画出照度数据 a+BA~|u^  
8. 在Matlab计算照度平均值 9hp0wi@W}  
9. 返回数据到FRED中 ZyWC_r!
