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。 3#Iq5vT  
=MvB9gx@r  
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: "y5bODq3t  
enableservice('AutomationServer', true) li{!Jp5]1b  
enableservice('AutomationServer') y;(G%s1  
#. 71O#!  
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。 xo2j fz

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: /,~g"y.;,  
1. 在FRED脚本编辑界面找到参考. 6J">@+  
2. 找到Matlab Automation Server Type Library <\ eRa{ef  
3. 将名字改为MLAPP ~,Yd.?.TI

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。 +DO<M1uE

现在将脚本代码公布如下,此脚本执行如下几个步骤: KzJJ@D*4M]  
1. 创建Matlab服务器。 JcMl*k  
2. 移动探测面对于前一聚焦面的位置。 G:@1.H`  
3. 在探测面追迹光线 dk"@2%xJ2d  
4. 在探测面计算照度 RS@[ +!:t  
5. 使用PutWorkspaceData发送照度数据到Matlab z.+%{_pe  
6. 使用PutFullMatrix发送标量场数据到Matlab中 j WMTQLE.  
7. 用Matlab画出照度数据 k3KT':*  
8. 在Matlab计算照度平均值 i g .  
9. 返回数据到FRED中 gdg``U;)p
