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。 =lu/9 i6  
G7CG~:3h+  
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: t2r?N}"P  
enableservice('AutomationServer', true) -@Uqz781  
enableservice('AutomationServer') bl'z<S, '  
5A4&+rdU  
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。 !Lh^oPT"I  
@ G4X  
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: eBJUv]o %  
1. 在FRED脚本编辑界面找到参考. 5P'p2x#U  
2. 找到Matlab Automation Server Type Library P06R JE  
3. 将名字改为MLAPP =2 *rA'im

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。 A?@@*$&

现在将脚本代码公布如下,此脚本执行如下几个步骤: a<h1\ `H7  
1. 创建Matlab服务器。 N72Yq)(  
2. 移动探测面对于前一聚焦面的位置。 EFc-foN  
3. 在探测面追迹光线 1DA1N<'  
4. 在探测面计算照度 ":nQgV\ 9  
5. 使用PutWorkspaceData发送照度数据到Matlab "{D|@Bc  
6. 使用PutFullMatrix发送标量场数据到Matlab中 2m~V{mUT!  
7. 用Matlab画出照度数据 h/,${,}J  
8. 在Matlab计算照度平均值 >G'SbQ8  
9. 返回数据到FRED中 W.w)H@]7m
