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。 Fn0 |v66  
})`z6d]3  
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: r7#.DJnN.  
enableservice('AutomationServer', true) Xy./1`X  
enableservice('AutomationServer') yVQW|D0,j  
RUq[HxF) 6  
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。 j;qV+Rq]t  
HRJ\H- V  
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: "%bU74>  
1. 在FRED脚本编辑界面找到参考. LqO=wK~  
2. 找到Matlab Automation Server Type Library ZNl1e'  
3. 将名字改为MLAPP \D};0#G0&

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。 orYZ<,u

现在将脚本代码公布如下,此脚本执行如下几个步骤: 7SN61)[m  
1. 创建Matlab服务器。 TyA1Qk\  
2. 移动探测面对于前一聚焦面的位置。 *2}f $8  
3. 在探测面追迹光线 +J~%z*A  
4. 在探测面计算照度 M IyT9",Pl  
5. 使用PutWorkspaceData发送照度数据到Matlab db=S*LUbl  
6. 使用PutFullMatrix发送标量场数据到Matlab中 "Bwmq9Jq  
7. 用Matlab画出照度数据 LitdO>%#2  
8. 在Matlab计算照度平均值 W'=}2Y$]u  
9. 返回数据到FRED中 *YX5bpR?
