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。 Pr'py  
F"I@=R-n  
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: mmti3Y  
enableservice('AutomationServer', true) V#Eq74ic  
enableservice('AutomationServer') K[Kc'6G  
Ns{4BM6j  
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。 lC{m;V2  
PT=%]o]  
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: i[swOY z]X  
1. 在FRED脚本编辑界面找到参考. &kGSxYDk%  
2. 找到Matlab Automation Server Type Library NaIVKo  
3. 将名字改为MLAPP l!2.)F`x

L'(^[vR(  
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。 Uz6B\-(0p

现在将脚本代码公布如下,此脚本执行如下几个步骤: SJfsFi?n  
1. 创建Matlab服务器。 qH$p]+Rk 5  
2. 移动探测面对于前一聚焦面的位置。 f>o@Y]/l  
3. 在探测面追迹光线 Ek:u[Uw\  
4. 在探测面计算照度 a fjC~}  
5. 使用PutWorkspaceData发送照度数据到Matlab "+Kr1nW  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Mg].#  
7. 用Matlab画出照度数据 t{ 'QMX  
8. 在Matlab计算照度平均值 =1D*K%  
9. 返回数据到FRED中 '7$v@Tvnre
