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。 3fM8W> *7  
T1_O~<  
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: kZ>_m &g  
enableservice('AutomationServer', true) gE\&[;)DB  
enableservice('AutomationServer') ,` 6O{Z~  
DS%~'S  
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。 A+de;&  
j4k\5~yzS  
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: L 4V,y>  
1. 在FRED脚本编辑界面找到参考. ?(0=+o(`  
2. 找到Matlab Automation Server Type Library :m]H?vq] \  
3. 将名字改为MLAPP #oW" 3L{,

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。 k<Qhw)M8

现在将脚本代码公布如下,此脚本执行如下几个步骤: Ql"kJ_F!br  
1. 创建Matlab服务器。 0$ JH5RC  
2. 移动探测面对于前一聚焦面的位置。 2*Zk^h=  
3. 在探测面追迹光线 p>_Qns7W  
4. 在探测面计算照度 =HMa<"-8  
5. 使用PutWorkspaceData发送照度数据到Matlab ' Dp;fEU$  
6. 使用PutFullMatrix发送标量场数据到Matlab中 UE8j8U'L  
7. 用Matlab画出照度数据 R!f<6l8#W  
8. 在Matlab计算照度平均值 YLJ^R$pi  
9. 返回数据到FRED中 `>)[UG!:|
