FRED如何调用Matlab

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。 ooL!TS GD  
Sh~dwxp*"  
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: Ae^~Cz1qz  
enableservice('AutomationServer', true) >~sI8czR*  
enableservice('AutomationServer') p8H'{f\G  
D/B8tf+V  
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。 u+e{Mim  
y8Z_Itlf  
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: +I:Unp  
1. 在FRED脚本编辑界面找到参考. B6nX$T4zP  
2. 找到Matlab Automation Server Type Library vq0Tk bzs  
3. 将名字改为MLAPP eKLZt%=  
[nG<[<0G;  
]z;I _-  
在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 `?qF$g9u~

现在将脚本代码公布如下,此脚本执行如下几个步骤: IH&|Tcf\  
1. 创建Matlab服务器。 nH'e?>x~e  
2. 移动探测面对于前一聚焦面的位置。 _LUhZlw  
3. 在探测面追迹光线 b:m88AG  
4. 在探测面计算照度 sPQQ"|wU  
5. 使用PutWorkspaceData发送照度数据到Matlab $}q23  
6. 使用PutFullMatrix发送标量场数据到Matlab中 \?ZB]*Fu  
7. 用Matlab画出照度数据 |A9F\A->4  
8. 在Matlab计算照度平均值 wn, KY$/  
9. 返回数据到FRED中 l^-];|Y
