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。 }~"hC3w

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: 2Fz|fW_  
enableservice('AutomationServer', true) (y?I Tz9  
enableservice('AutomationServer') 3,]gEE3  
Kx=4~  
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。 jS+AGE?5e

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: KN?6;G{  
1. 在FRED脚本编辑界面找到参考. ,RgB$TcE  
2. 找到Matlab Automation Server Type Library /}Lt,9  
3. 将名字改为MLAPP D K=cVpN%s

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。 UN%Vg:=

1. 创建Matlab服务器。 sf]s",t~J  
2. 移动探测面对于前一聚焦面的位置。 6gT5O]]#o  
3. 在探测面追迹光线 <JV"@H=  
4. 在探测面计算照度 @FC"nM  
5. 使用PutWorkspaceData发送照度数据到Matlab n @?4b8"  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ZxlAk+<]  
7. 用Matlab画出照度数据 f{"8g"[[)(  
8. 在Matlab计算照度平均值 7C$ 5  
9. 返回数据到FRED中 p/2jh&
