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。 K 0R<a~  
as6a)t.^  
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: $DBJ"8n2  
enableservice('AutomationServer', true) DvhJkdLB>  
enableservice('AutomationServer') R <}UT  
>UlAae44  
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。 = wEU+R_#o

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: Z7)la |  
1. 在FRED脚本编辑界面找到参考. =MMU(0 E  
2. 找到Matlab Automation Server Type Library N;gI %6  
3. 将名字改为MLAPP M<$a OW0

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。 4;_aFn

现在将脚本代码公布如下,此脚本执行如下几个步骤: ;XAj/6pm  
1. 创建Matlab服务器。 J?DJA2o  
2. 移动探测面对于前一聚焦面的位置。 v@n0ma=  
3. 在探测面追迹光线 !Z(3dtUy  
4. 在探测面计算照度 HFlMx  
5. 使用PutWorkspaceData发送照度数据到Matlab `?P)RS30  
6. 使用PutFullMatrix发送标量场数据到Matlab中 4}&$s  
7. 用Matlab画出照度数据 : ZehBu  
8. 在Matlab计算照度平均值 N #C,q&;  
9. 返回数据到FRED中 ey!QAEg"X1
