[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。 1KYN>s:  
?v-1zCls  
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： S }>n1F_
 
enableservice('AutomationServer', true) hGf-q?7  
enableservice('AutomationServer') E&B{5/rv  
|7^^*UzSK:  
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。 [ "xn5lE  
.]|Zf!>}s  
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： 7rHS^8'H&  
1. 在FRED脚本编辑界面找到参考. 111D3  
2. 找到Matlab Automation Server Type Library !Do,>gO  
3. 将名字改为MLAPP M3z

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。 8#` 6M5

现在将脚本代码公布如下，此脚本执行如下几个步骤： oY`qInM_  
1. 创建Matlab服务器。 w.N,)]h  
2. 移动探测面对于前一聚焦面的位置。 #ycL'T`X%  
3. 在探测面追迹光线 9zgNjjCl]  
4. 在探测面计算照度 :o"8MZp  
5. 使用PutWorkspaceData发送照度数据到Matlab <3hA!$o~  
6. 使用PutFullMatrix发送标量场数据到Matlab中 a)2yE,":  
7. 用Matlab画出照度数据 +dkS/b  
8. 在Matlab计算照度平均值 Q;nAPS  
9. 返回数据到FRED中 #\bP7a+
