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。 T6ZJSKM

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: Eh)VU_D  
enableservice('AutomationServer', true) 7l})`> k  
enableservice('AutomationServer') ^(0tNX/XD  
S-:7P.#Q  
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。 9/k?Lv

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: 5B<G;if,  
1. 在FRED脚本编辑界面找到参考. zA/W+j$:  
2. 找到Matlab Automation Server Type Library D{,B[5  
3. 将名字改为MLAPP h;KI2k_^

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。 wzMWuA4vX

现在将脚本代码公布如下,此脚本执行如下几个步骤: qpl"j-  
1. 创建Matlab服务器。 2r~ Nh](  
2. 移动探测面对于前一聚焦面的位置。 @$79$:q N  
3. 在探测面追迹光线 I$`Vw >  
4. 在探测面计算照度 o+O\VNW  
5. 使用PutWorkspaceData发送照度数据到Matlab 2/B Flb  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ZX.VzZS  
7. 用Matlab画出照度数据 ':!;6v|L  
8. 在Matlab计算照度平均值 9_ Qm_  
9. 返回数据到FRED中 ):+H`Hcm
