[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。 5rck]L'  
gU|:Y&lFZg  
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： H9ES|ZJs  
enableservice('AutomationServer', true) g3[-[G
^5  
enableservice('AutomationServer') [[<TW}  
25vjn 1$sW  
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。 rYdNn0mhk

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： 8M,o)oH  
1. 在FRED脚本编辑界面找到参考. WLj]EsA.  
2. 找到Matlab Automation Server Type Library X=m^+%iD  
3. 将名字改为MLAPP sPW:[  
:P2!& W  
:ZB.I(v  
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。 %regt{

1. 创建Matlab服务器。 xsRkO9x  
2. 移动探测面对于前一聚焦面的位置。 5;/q[oXI  
3. 在探测面追迹光线 Os>&:{D4!  
4. 在探测面计算照度 Ty{ SZUJ  
5. 使用PutWorkspaceData发送照度数据到Matlab @#W4?L*D  
6. 使用PutFullMatrix发送标量场数据到Matlab中 J>T98y/))  
7. 用Matlab画出照度数据 ub>:dNBN  
8. 在Matlab计算照度平均值 UTu~"uCR  
9. 返回数据到FRED中 P
