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。 Onao'sjY  
gO29:L[t  
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: ~O!v?2it8q  
enableservice('AutomationServer', true) [1Rs~T"  
enableservice('AutomationServer') lq74Fz&(  
&0'BCT  
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。 dXZV1e1b&#

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: #-{4F?DA]y  
1. 在FRED脚本编辑界面找到参考. +]G;_/[2  
2. 找到Matlab Automation Server Type Library C 7v 8  
3. 将名字改为MLAPP i -+B{H

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。 uTQ/_$

现在将脚本代码公布如下,此脚本执行如下几个步骤: c}QjKJ-c  
1. 创建Matlab服务器。 {=TD^>?  
2. 移动探测面对于前一聚焦面的位置。 _|3n h;-m  
3. 在探测面追迹光线 o`G@Je_}x  
4. 在探测面计算照度 a4?:suX$  
5. 使用PutWorkspaceData发送照度数据到Matlab 6 LC*X  
6. 使用PutFullMatrix发送标量场数据到Matlab中 YQ&Xd/z-  
7. 用Matlab画出照度数据 qvCl mZ  
8. 在Matlab计算照度平均值 y 2bZo'Z  
9. 返回数据到FRED中 DEIn:d
