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。 .kl.awT  
y E; n. L  
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: [iO*t, 3@h  
enableservice('AutomationServer', true) qV7F=1k]  
enableservice('AutomationServer') 4qYT  
z1AYXW6F  
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。 u&E$(  
ZUA%ZkX=F  
在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: _aaQ1A`p  
1. 在FRED脚本编辑界面找到参考. F%-KY$%  
2. 找到Matlab Automation Server Type Library ='[J.  
3. 将名字改为MLAPP fPpFAO  
~MpcVI_K  
3g{T+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。 ~43T$^<w;

现在将脚本代码公布如下,此脚本执行如下几个步骤: j,Vir"-)  
1. 创建Matlab服务器。 L>ruNw'-K  
2. 移动探测面对于前一聚焦面的位置。 -50 Nd=1  
3. 在探测面追迹光线 #}lq2!f6  
4. 在探测面计算照度 o4U[;.?c  
5. 使用PutWorkspaceData发送照度数据到Matlab yGs:3KI  
6. 使用PutFullMatrix发送标量场数据到Matlab中 32S5Ai@Cd"  
7. 用Matlab画出照度数据 'CfM'f3uu  
8. 在Matlab计算照度平均值 iD(+\:E  
9. 返回数据到FRED中 LJh^-FQ
