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。 \n9zw'  
DQwGUF'(  
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: 5Zw1y@k(  
enableservice('AutomationServer', true) /.M+fr S  
enableservice('AutomationServer') 7OW bAu;  
;+1RU v  
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。 ^*~;k|;&  
M,}|tsL  
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: ps$7bN C  
1. 在FRED脚本编辑界面找到参考. <5=JE*s$NS  
2. 找到Matlab Automation Server Type Library RI2f`p8k  
3. 将名字改为MLAPP g/CxXSv@0

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。 5d@t7[]

现在将脚本代码公布如下,此脚本执行如下几个步骤: ~XeFOM q  
1. 创建Matlab服务器。 !.1%}4@Q]  
2. 移动探测面对于前一聚焦面的位置。 i@NqC;~;  
3. 在探测面追迹光线 m`6Yc:@E  
4. 在探测面计算照度 !EQ@#qW/  
5. 使用PutWorkspaceData发送照度数据到Matlab - y9>;6  
6. 使用PutFullMatrix发送标量场数据到Matlab中 i ZL2p>  
7. 用Matlab画出照度数据 E2L(wt}^  
8. 在Matlab计算照度平均值 Vx_rc%'  
9. 返回数据到FRED中 aCV4AyG
