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。 | I_,;c  
6b9 oSY-8  
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: TFbMrIF  
enableservice('AutomationServer', true) ]de'v  
enableservice('AutomationServer') Y27x;U  
-4|\,=j  
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。 &ah!g!o3

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(mZ#*vdY  
1. 在FRED脚本编辑界面找到参考. f>k<I[C<  
2. 找到Matlab Automation Server Type Library 5?+ECxPt  
3. 将名字改为MLAPP {VBx;A3*I

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。 " (c#H

现在将脚本代码公布如下,此脚本执行如下几个步骤: g9> 0N#<  
1. 创建Matlab服务器。 9ALE6  
2. 移动探测面对于前一聚焦面的位置。 E 5D5  
3. 在探测面追迹光线 ~|e?@3_G  
4. 在探测面计算照度 V!#+Ti/w4  
5. 使用PutWorkspaceData发送照度数据到Matlab .i[rd4MCK  
6. 使用PutFullMatrix发送标量场数据到Matlab中 i3~"qbU%z[  
7. 用Matlab画出照度数据 J<h^V+x  
8. 在Matlab计算照度平均值 &kKopJH  
9. 返回数据到FRED中 X{A|{u=
