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。 o XFo  
Msst:}QY  
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: OVUJiBp  
enableservice('AutomationServer', true) nw,XA0M3  
enableservice('AutomationServer') 9,cMb)=0  
;)23@6{R%  
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。 1)t*l;.

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: wBI>H 7A  
1. 在FRED脚本编辑界面找到参考. *nx$r[Mqj  
2. 找到Matlab Automation Server Type Library %Xe 74C"  
3. 将名字改为MLAPP W4p4[&c|

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。 VM}7 ~

现在将脚本代码公布如下,此脚本执行如下几个步骤: ["WWaCcx  
1. 创建Matlab服务器。 /N7.|XI.  
2. 移动探测面对于前一聚焦面的位置。 a\B'Qe+  
3. 在探测面追迹光线 +!cibTQTT  
4. 在探测面计算照度 cnz+%Y N  
5. 使用PutWorkspaceData发送照度数据到Matlab c>%%'c  
6. 使用PutFullMatrix发送标量场数据到Matlab中 h'.B-y~c  
7. 用Matlab画出照度数据 iI Dun Ih  
8. 在Matlab计算照度平均值 ows 3%  
9. 返回数据到FRED中 ;[B-!F>
