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。 ey]WoUZ  
v]GQb  
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: [C#H _y(  
enableservice('AutomationServer', true) :Ahw{z`H#  
enableservice('AutomationServer') OWys`2W  
g-~]^$  
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。 GY t|[GC

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: m9=93W?   
1. 在FRED脚本编辑界面找到参考. $'x#rW>v  
2. 找到Matlab Automation Server Type Library 60R]Q  
3. 将名字改为MLAPP %a:>3! +

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。 G,}"}v:

现在将脚本代码公布如下,此脚本执行如下几个步骤: Js<DVe,  
1. 创建Matlab服务器。 r>ag( ^J\  
2. 移动探测面对于前一聚焦面的位置。 ]]NTvr  
3. 在探测面追迹光线 !%'"l{R  
4. 在探测面计算照度 P~*'/!@  
5. 使用PutWorkspaceData发送照度数据到Matlab (nwp s  
6. 使用PutFullMatrix发送标量场数据到Matlab中 $jOp:R&I^3  
7. 用Matlab画出照度数据 5uX-onP\[  
8. 在Matlab计算照度平均值 x }@P  
9. 返回数据到FRED中 I8/tD|3
