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。 H_,4N_hL  
hXvC>ie(i  
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: gF`hlYD  
enableservice('AutomationServer', true) Vju/+  
enableservice('AutomationServer') !L( )3=  
-g:i'e  
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。 [+8*}03

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: r9*6=*J|  
1. 在FRED脚本编辑界面找到参考. 97 ,Yq3  
2. 找到Matlab Automation Server Type Library (&u'S+  
3. 将名字改为MLAPP AQ0zsy  
"&{.g1i9  
&bGf{P*Da  
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。 'Fc$?$c\

现在将脚本代码公布如下,此脚本执行如下几个步骤: EG|_YW7  
1. 创建Matlab服务器。 4;@L#Pzt  
2. 移动探测面对于前一聚焦面的位置。 r i)`e  
3. 在探测面追迹光线 ZmycK:f  
4. 在探测面计算照度 f3 imkZ(  
5. 使用PutWorkspaceData发送照度数据到Matlab R](cko=  
6. 使用PutFullMatrix发送标量场数据到Matlab中 0x<G\ l4  
7. 用Matlab画出照度数据 +=d=  
8. 在Matlab计算照度平均值 >vR2K^  
9. 返回数据到FRED中 j<6+p r
