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。 J3Ipk-'lx  
K q;X(&Z  
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: m2wGg/F5  
enableservice('AutomationServer', true) ;vM&se63  
enableservice('AutomationServer') lu~<pfg  
^P30g2gv>  
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。 e}%~S9\UL5  
E= 3Ui  
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: 8T ?=_|  
1. 在FRED脚本编辑界面找到参考. xgsEJE  
2. 找到Matlab Automation Server Type Library fmqHWu*wG  
3. 将名字改为MLAPP D#VUx9kugv  
# .1+-^TQk  
`M0m`Up  
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。 8YroEX[5l

现在将脚本代码公布如下,此脚本执行如下几个步骤: tzH~[n,  
1. 创建Matlab服务器。 a=m4)tjk  
2. 移动探测面对于前一聚焦面的位置。 44e:K5;]7  
3. 在探测面追迹光线 .|ZO2MCd  
4. 在探测面计算照度 ~kHWh8\b:  
5. 使用PutWorkspaceData发送照度数据到Matlab Uwj|To&QR  
6. 使用PutFullMatrix发送标量场数据到Matlab中 =$kSvCjP  
7. 用Matlab画出照度数据 ;UU`kk  
8. 在Matlab计算照度平均值 ,x (?7ZW>  
9. 返回数据到FRED中 be^+X[
