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。 2u"lc'9v  
W(,j2pU  
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: bsIG1&n'T  
enableservice('AutomationServer', true) __=H"UhWv  
enableservice('AutomationServer') AK:cDKBO  
;_<R +w3-  
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。 @:lM|2:

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: ']_2@<XW)  
1. 在FRED脚本编辑界面找到参考. SQKhht`M  
2. 找到Matlab Automation Server Type Library Q;M\fBQO}&  
3. 将名字改为MLAPP ZN[<=w&(cB

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。 ;nY#/%f

现在将脚本代码公布如下,此脚本执行如下几个步骤: yI0bSu<j-  
1. 创建Matlab服务器。 9t`;~)o  
2. 移动探测面对于前一聚焦面的位置。 K,b M9>}  
3. 在探测面追迹光线 Q8p6n  
4. 在探测面计算照度 7T~ M`$h  
5. 使用PutWorkspaceData发送照度数据到Matlab 04a ^jjc  
6. 使用PutFullMatrix发送标量场数据到Matlab中 F:{*4b  
7. 用Matlab画出照度数据 k+<9 45kC  
8. 在Matlab计算照度平均值 ;b~ S/   
9. 返回数据到FRED中 g: i5%1
