[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。 p{pzOMi6  
T[2f6[#[_  
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： lQ(BEv"2G[  
enableservice('AutomationServer', true) smQpIB;  
enableservice('AutomationServer') 5d>YE  
kkuQ"^<J  
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。 hghto \G5Y

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： #+5mpDh  
1. 在FRED脚本编辑界面找到参考. E* DVQ3~  
2. 找到Matlab Automation Server Type Library mk3e^,[A  
3. 将名字改为MLAPP HZ`G)1&)

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。 I}CA-8

现在将脚本代码公布如下，此脚本执行如下几个步骤： "/]tFY%Y  
1. 创建Matlab服务器。 d?+oT0pCH  
2. 移动探测面对于前一聚焦面的位置。 N

3. 在探测面追迹光线 'V1 -iJj9  
4. 在探测面计算照度 GeW$lA I  
5. 使用PutWorkspaceData发送照度数据到Matlab d"$oV~>P|  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Bv|9{:1%X}  
7. 用Matlab画出照度数据 q\Io6=39x  
8. 在Matlab计算照度平均值 ""KN?qh9  
9. 返回数据到FRED中 \:)o'-
