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。 V sl,u  
U52 V1b  
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: (Q=o 9o:b  
enableservice('AutomationServer', true)  FNH)wk  
enableservice('AutomationServer') igA?E56?  
&Jj|+P-lY  
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。 ,H+Y1N4W(

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: 1k4\zVgi  
1. 在FRED脚本编辑界面找到参考. ljZRz$y  
2. 找到Matlab Automation Server Type Library |Qcz5M90e  
3. 将名字改为MLAPP ,Kj>F2{  
JH]S'5X8K  
GxD`M2  
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。 (@XQ]S}L

现在将脚本代码公布如下,此脚本执行如下几个步骤: P1rjF:x[*  
1. 创建Matlab服务器。 R;Dj70g  
2. 移动探测面对于前一聚焦面的位置。 f EL 9J{  
3. 在探测面追迹光线 !38KHq^|&  
4. 在探测面计算照度 g@!U^mr*3  
5. 使用PutWorkspaceData发送照度数据到Matlab B_ict)}ld  
6. 使用PutFullMatrix发送标量场数据到Matlab中 /g+-{+sx  
7. 用Matlab画出照度数据 %p  
8. 在Matlab计算照度平均值 p2 1|  
9. 返回数据到FRED中 ugTsI~aE
