[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。 "~ $i#  
S g1[p#U  
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： =gJ{75tV3  
enableservice('AutomationServer', true) w8Z#]kRv
 
enableservice('AutomationServer') XPMUhozV
 
pA_u;*  
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。 #\Y`?

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： hLZfArq}  
1. 在FRED脚本编辑界面找到参考. ^1Fzs(#.  
2. 找到Matlab Automation Server Type Library 'R-\6;3E>9  
3. 将名字改为MLAPP +kYp!00

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。 [efU)O&

1. 创建Matlab服务器。 My

2. 移动探测面对于前一聚焦面的位置。 Q) aZ0 Pt  
3. 在探测面追迹光线 _)= e`9%  
4. 在探测面计算照度 &XcPHZy'  
5. 使用PutWorkspaceData发送照度数据到Matlab Qu'#~#L`  
6. 使用PutFullMatrix发送标量场数据到Matlab中 kBC$dW-  
7. 用Matlab画出照度数据 l\AdL$$Mb  
8. 在Matlab计算照度平均值 2Ul8<${c{  
9. 返回数据到FRED中 ,GVX1B?
