[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。 b.;F)(  
L[Tr"BW  
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： g^4'42UX  
enableservice('AutomationServer', true) Hco[p+  
enableservice('AutomationServer') ks:Z=%o   
ewY+a ,t  
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。 hPD2/M

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： ? vk;b!  
1. 在FRED脚本编辑界面找到参考. mqw&SxU9  
2. 找到Matlab Automation Server Type Library K`PF|=z  
3. 将名字改为MLAPP ?5jkb

k+&LOb7  
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。 tE=

现在将脚本代码公布如下，此脚本执行如下几个步骤： yH@W6'.  
1. 创建Matlab服务器。 "P"~/<:)  
2. 移动探测面对于前一聚焦面的位置。 <gQw4  
3. 在探测面追迹光线 N1+%[Uh9)  
4. 在探测面计算照度 9.D'!  
5. 使用PutWorkspaceData发送照度数据到Matlab cZ%weQa#N)  
6. 使用PutFullMatrix发送标量场数据到Matlab中 W@JmG`Sy  
7. 用Matlab画出照度数据 W32bBzhL  
8. 在Matlab计算照度平均值 W?5^cEF  
9. 返回数据到FRED中 -HS(<V=a?k
