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。 {ES3nCL(8  
Y|Z*|c.4OK  
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'I-#  
enableservice('AutomationServer', true) L(iWFy1& T  
enableservice('AutomationServer') \ /o`CV{O  
V`G]4}  
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。 PR6{Y]e%

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: n@xU5Q  
1. 在FRED脚本编辑界面找到参考. tjGQ0-Lo  
2. 找到Matlab Automation Server Type Library m}k rG  
3. 将名字改为MLAPP &BP%~  
yB&s2J  
6j0!$q^  
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。 Nt/>RCh

现在将脚本代码公布如下,此脚本执行如下几个步骤:  'y1=Z  
1. 创建Matlab服务器。 60*=Bs%b  
2. 移动探测面对于前一聚焦面的位置。 2x0[@cT i?  
3. 在探测面追迹光线 YOqBIbp~&)  
4. 在探测面计算照度 4Xlq Ym  
5. 使用PutWorkspaceData发送照度数据到Matlab XvWUJ6M  
6. 使用PutFullMatrix发送标量场数据到Matlab中 mI-$4st]  
7. 用Matlab画出照度数据 VCtj8hKDr  
8. 在Matlab计算照度平均值 P)4SrqW_  
9. 返回数据到FRED中 gW RSS=8%
