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。 h[dJNawL  
A.*e8a/6X  
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: dEYw_qJ2  
enableservice('AutomationServer', true) tQ@7cjq8bA  
enableservice('AutomationServer') $7YZ;=~B  
@PM<pEve  
结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 = cRmaD  
T;DKDg a  
在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: |kZ!-?9Z  
1. 在FRED脚本编辑界面找到参考. 2#NnA3l]x%  
2. 找到Matlab Automation Server Type Library @ 95p[  
3. 将名字改为MLAPP @7}XBg[pI  
!,ODczWvh  
z uNm !$  
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。 YC;@^

现在将脚本代码公布如下,此脚本执行如下几个步骤: RF*>U a  
1. 创建Matlab服务器。 ~ 6=6YP  
2. 移动探测面对于前一聚焦面的位置。 ZC2aIJ  
3. 在探测面追迹光线 Foq3==*p  
4. 在探测面计算照度 qJF'KHyU{l  
5. 使用PutWorkspaceData发送照度数据到Matlab !84Lvg0&  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ,R=!ts[qi  
7. 用Matlab画出照度数据 )xf(4  
8. 在Matlab计算照度平均值 $cn8]*Z =  
9. 返回数据到FRED中 m> +
