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。 Z-:T')#Cf  
`3g5n:"g\  
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: V_zU?}lZ^  
enableservice('AutomationServer', true) GHY+q{'#V_  
enableservice('AutomationServer') A*G ~#v^  
G>=Fdt7Oc  
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。 zX lcu_rc  
!#d5hjoX  
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: <p/zm}?')  
1. 在FRED脚本编辑界面找到参考. `J] e.K  
2. 找到Matlab Automation Server Type Library \#4mPk_"  
3. 将名字改为MLAPP pu~b\&^G

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。 )pSA|Qt N

现在将脚本代码公布如下,此脚本执行如下几个步骤: ]~2iducB,  
1. 创建Matlab服务器。 |sdG<+  
2. 移动探测面对于前一聚焦面的位置。 :_}xN!9LA  
3. 在探测面追迹光线 Om^(CAp  
4. 在探测面计算照度 Sl/]1[|mb  
5. 使用PutWorkspaceData发送照度数据到Matlab ,Qx]_gZ`  
6. 使用PutFullMatrix发送标量场数据到Matlab中 }`kiULC'=  
7. 用Matlab画出照度数据 -L +kt_>  
8. 在Matlab计算照度平均值 7Xx3s@  
9. 返回数据到FRED中 nNq<x^@83
