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。 \34:]NM  
4i"fHVp8  
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: cCG!X%9  
enableservice('AutomationServer', true) lxR]Bh+  
enableservice('AutomationServer') :{KpnJvd  
:"K9(XKKU  
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。 @qF:v]=_@

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: =W gzj|Kr  
1. 在FRED脚本编辑界面找到参考. z6Nz)$!_i  
2. 找到Matlab Automation Server Type Library -O $!sFmY  
3. 将名字改为MLAPP A5s;<d0

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。 Fc^!="H

现在将脚本代码公布如下,此脚本执行如下几个步骤: '*G8;91u  
1. 创建Matlab服务器。 #w!ewCvt  
2. 移动探测面对于前一聚焦面的位置。 +Ur75YPh  
3. 在探测面追迹光线 c? Mbyay  
4. 在探测面计算照度 ]na$n[T/I  
5. 使用PutWorkspaceData发送照度数据到Matlab @oD2_D2  
6. 使用PutFullMatrix发送标量场数据到Matlab中 Jpn= ^f[rm  
7. 用Matlab画出照度数据 2r@9|}La  
8. 在Matlab计算照度平均值 +iNp8  
9. 返回数据到FRED中 dleCh+ny?
