FRED案例-FRED如何调用Matlab

b:d.Lf{y7  
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。 Y?SJQhN6W  
<qj@waKw4  
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: E]Gq!fA&<  
enableservice('AutomationServer', true) Fl(ZKpSZU  
    enableservice('AutomationServer') |`9zE]  
y]z#??  
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。 HE .Dl7 {  
Gqu0M`+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: i*rv_G|(Zj  
1. 在FRED脚本编辑界面找到参考. sU3V)7"  
2. 找到Matlab Automation Server Type Library kR|DzB7  
    3. 将名字改为MLAPP leqSS}KU+  
     $R}iL  
     L7'X7WYf&  
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。 ,UJPLj^

现在将脚本代码公布如下,此脚本执行如下几个步骤: 9jFDBy+  
1. 创建Matlab服务器。 d~s-;T  
2. 移动探测面对于前一聚焦面的位置。 H0Xda.Y(  
3. 在探测面追迹光线 ep1Ajz.l  
4. 在探测面计算照度 GdwHm  
5. 使用PutWorkspaceData发送照度数据到Matlab !f[N&se  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Tfs9< k>G#  
7. 用Matlab画出照度数据 X7!A(q+h  
8. 在Matlab计算照度平均值 #3jZ7RqzQ  
9. 返回数据到FRED中 $w}aX0dK&
