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。 6S{l' !s'  
Uw:"n]G]D?  
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: HVAYPerH  
enableservice('AutomationServer', true) #0<XNLM  
enableservice('AutomationServer') xYB{;K  
W%Fv p;\`  
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。 K)P%;X

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: Vt ohL+  
1. 在FRED脚本编辑界面找到参考. 1 TXioDs=_  
2. 找到Matlab Automation Server Type Library X wtqi@zlE  
3. 将名字改为MLAPP 2A!FDr~cdT

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。 & nK<:^n

现在将脚本代码公布如下,此脚本执行如下几个步骤: e:W{OIz:  
1. 创建Matlab服务器。 Bbp|!+KP{(  
2. 移动探测面对于前一聚焦面的位置。 *lb<$E]="!  
3. 在探测面追迹光线 }PpUAt~g  
4. 在探测面计算照度 6H|S;K+  
5. 使用PutWorkspaceData发送照度数据到Matlab .G\7cZ  
6. 使用PutFullMatrix发送标量场数据到Matlab中 3 gf1ownC  
7. 用Matlab画出照度数据 zW nR6*\  
8. 在Matlab计算照度平均值 fc@A0Hf  
9. 返回数据到FRED中 B7%U_F|m
