[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。 @c}Gw;e  
Q |hBGH9:B  
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： %&J`mq  
enableservice('AutomationServer', true) 4b}'W}  
enableservice('AutomationServer') #A:^XAU1Z@  
~+PKWs'}F  
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。

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： v!=e]w6{  
1. 在FRED脚本编辑界面找到参考.

2. 找到Matlab Automation Server Type Library s !II}'Je  
3. 将名字改为MLAPP X?]Mzcu

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。 Hi U/fi`

现在将脚本代码公布如下，此脚本执行如下几个步骤： waG &3m  
1. 创建Matlab服务器。 ca[*#xiJ  
2. 移动探测面对于前一聚焦面的位置。 rLbFaLeQ  
3. 在探测面追迹光线 )ri'W <l  
4. 在探测面计算照度 |aj]]l[@S  
5. 使用PutWorkspaceData发送照度数据到Matlab Ifq|MZ\  
6. 使用PutFullMatrix发送标量场数据到Matlab中 2\gbciJ[{(  
7. 用Matlab画出照度数据 e.(RhajB  
8. 在Matlab计算照度平均值 Z*(OcQ-  
9. 返回数据到FRED中 0:x+;R<P*w
