[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。 ~\s &]L  
1eR{~ ,  
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： )yH#*~X_  
enableservice('AutomationServer', true) YrcC"  
enableservice('AutomationServer') 9(
evHR7  
*[5#g3  
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。 T9;o.f 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： =<W[dV=W  
1. 在FRED脚本编辑界面找到参考. XxU}|jTO#  
2. 找到Matlab Automation Server Type Library 89e.\EH  
3. 将名字改为MLAPP Ex&RR< 5

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。 ~~E=E;9

1. 创建Matlab服务器。 s#Y7*?Sm  
2. 移动探测面对于前一聚焦面的位置。 W)P_t"'@L  
3. 在探测面追迹光线 |;1:$E"  
4. 在探测面计算照度 c+M@{EbuN  
5. 使用PutWorkspaceData发送照度数据到Matlab 2{tJ'3  
6. 使用PutFullMatrix发送标量场数据到Matlab中 a}]@o"  
7. 用Matlab画出照度数据 ^?VT y5yp  
8. 在Matlab计算照度平均值 qpH-P8V   
9. 返回数据到FRED中 ~,4Znuin
