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。 \hI?XnL#  
oI`Mn3N  
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: 3  ;F  
enableservice('AutomationServer', true) g8'8"9:xC  
enableservice('AutomationServer') :, v(l q  
_hl| 3 eW5  
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。 D}}?{pe

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: bG"FN/vg  
1. 在FRED脚本编辑界面找到参考. 3k>#z%//  
2. 找到Matlab Automation Server Type Library :epB:r  
3. 将名字改为MLAPP RJ0,7 E<B

uMG y-c  
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。 LzLJ6A>;R

现在将脚本代码公布如下,此脚本执行如下几个步骤: |zfFB7}v  
1. 创建Matlab服务器。 mMZrBz7r  
2. 移动探测面对于前一聚焦面的位置。 <W3p!  
3. 在探测面追迹光线 Gl w|*{$  
4. 在探测面计算照度 cf>lY  
5. 使用PutWorkspaceData发送照度数据到Matlab 2<n 18-|OQ  
6. 使用PutFullMatrix发送标量场数据到Matlab中 "8z Me L  
7. 用Matlab画出照度数据  Jn|<G  
8. 在Matlab计算照度平均值 *wmkcifF;  
9. 返回数据到FRED中 Cpd>xXZz&S
