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。 i{Uc6 R6  
z#8~iF1  
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: v6[!o<@"a  
enableservice('AutomationServer', true) ED2a}Tt>Z  
enableservice('AutomationServer') }'5MK  
10G}{  
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。 xj<Rp|7&

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: %"kPvI3Y  
1. 在FRED脚本编辑界面找到参考. +s"hqm  
2. 找到Matlab Automation Server Type Library }Q)#[#e  
3. 将名字改为MLAPP l3KVW5-!gS  
dl.N.P7}4  
a_[Eh fE  
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。 &LmJ!^#

现在将脚本代码公布如下,此脚本执行如下几个步骤: 4qN{n#{+]  
1. 创建Matlab服务器。 K#l:wH _  
2. 移动探测面对于前一聚焦面的位置。 @:;)~V  
3. 在探测面追迹光线 a[v0%W ]u  
4. 在探测面计算照度 q?,).x nN  
5. 使用PutWorkspaceData发送照度数据到Matlab w4_ U0 n3  
6. 使用PutFullMatrix发送标量场数据到Matlab中 w:??h4lt  
7. 用Matlab画出照度数据 #&cI3i  
8. 在Matlab计算照度平均值 1;d$#j  
9. 返回数据到FRED中 ]fm'ZY&
