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。 ]J2:194  
=wi*Nd7L  
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: n uQM^2  
enableservice('AutomationServer', true) )<4_:  
enableservice('AutomationServer') T_<BVM  
Cup@TET35  
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。 $t rAC@3O@  
-m 5}#P89  
在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ]r]k-GZ$  
1. 在FRED脚本编辑界面找到参考. [LM^), J?  
2. 找到Matlab Automation Server Type Library 0m9ZQ O  
3. 将名字改为MLAPP qBk``!|s]

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。 Ja^ 5?Ar|

现在将脚本代码公布如下,此脚本执行如下几个步骤: 5iFV;W  
1. 创建Matlab服务器。 K% KZO`gO  
2. 移动探测面对于前一聚焦面的位置。 ?T: jk4+  
3. 在探测面追迹光线 nw'-`*'rj  
4. 在探测面计算照度 q$ghLGz  
5. 使用PutWorkspaceData发送照度数据到Matlab jkrx]`A{~  
6. 使用PutFullMatrix发送标量场数据到Matlab中 j;P+_Hfe/E  
7. 用Matlab画出照度数据 j,%EW+j$  
8. 在Matlab计算照度平均值 eQX`,9:5  
9. 返回数据到FRED中 YwT-T,oD
