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。 ?J,K[.z  
`LOW)|6r`  
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: %PlA9@:IZ  
enableservice('AutomationServer', true) '\% Kd+k  
enableservice('AutomationServer') O^~Z-; FA  
8'* /|)Hn  
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。 Q#5~"C

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: rK[;wD<  
1. 在FRED脚本编辑界面找到参考. A4daIhP (  
2. 找到Matlab Automation Server Type Library V [Wo9Y\  
3. 将名字改为MLAPP [.'9Sw

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。 tF:AqR: (~

现在将脚本代码公布如下,此脚本执行如下几个步骤: )l H`a  
1. 创建Matlab服务器。 ] @uuB\u  
2. 移动探测面对于前一聚焦面的位置。 -sxu7I  
3. 在探测面追迹光线 lx<!*2 -^  
4. 在探测面计算照度 9~{,Hj1xE  
5. 使用PutWorkspaceData发送照度数据到Matlab X@ S~D7|ja  
6. 使用PutFullMatrix发送标量场数据到Matlab中 @xeJ$ rlu  
7. 用Matlab画出照度数据 l?B=5*0  
8. 在Matlab计算照度平均值 k_`h (R  
9. 返回数据到FRED中 6xLQ
