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。 rtZEK:.#  
7s}E q~  
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: N 2$uw@s  
enableservice('AutomationServer', true) @$!rgLyL[  
enableservice('AutomationServer') zL/r V<  
UA(&_-C\  
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。 3D2i32Y@!

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: b+e9Pi*\  
1. 在FRED脚本编辑界面找到参考. v)%0`%nSR  
2. 找到Matlab Automation Server Type Library tlpTq\;  
3. 将名字改为MLAPP ?[c{pb ,|  
{&0u:  
W|AK"vf  
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。 \,-e>

现在将脚本代码公布如下,此脚本执行如下几个步骤: ['Y"6[1  
1. 创建Matlab服务器。 G:i>MJbxT  
2. 移动探测面对于前一聚焦面的位置。 BY`vs+]XY  
3. 在探测面追迹光线 }}gtz-w  
4. 在探测面计算照度 s&F& *5W  
5. 使用PutWorkspaceData发送照度数据到Matlab HJt@m &H|  
6. 使用PutFullMatrix发送标量场数据到Matlab中 x<\5Jrqt  
7. 用Matlab画出照度数据 [K""6D  
8. 在Matlab计算照度平均值 >Q[3t79^  
9. 返回数据到FRED中 .njk^,N
