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。 a[TMDU;(/4  
k VQ\1!  
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: nQS|Lt_+  
enableservice('AutomationServer', true) [ikOb8 G#  
enableservice('AutomationServer') jZ; =so  
GPkpXVm  
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。 40 0#v|b

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: 4X|zmr:A  
1. 在FRED脚本编辑界面找到参考. t |oR7qa{w  
2. 找到Matlab Automation Server Type Library ;*&-C9b  
3. 将名字改为MLAPP WjqO@]P6  
Q NVa?'0"Y  
o _H`o&xr  
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。 S21,VpW\

现在将脚本代码公布如下,此脚本执行如下几个步骤: I++. ee  
1. 创建Matlab服务器。 N17RLz *\  
2. 移动探测面对于前一聚焦面的位置。 Z EO WO  
3. 在探测面追迹光线 ^sg,\zD 'X  
4. 在探测面计算照度 "C3/T&F  
5. 使用PutWorkspaceData发送照度数据到Matlab 6S\8$  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ,6W>can  
7. 用Matlab画出照度数据 WOf 4o  
8. 在Matlab计算照度平均值 C{wEzM :  
9. 返回数据到FRED中 N)>ID(}F1
