[技术]FRED如何调用Matlab [复制链接]

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。 T^Y([23

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： 4[.oPK=i  
enableservice('AutomationServer', true) <D:.(AUeO  
enableservice('AutomationServer') 1M}5>V{  
V,mw[Hw  
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。 ur3(HL

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： 7Nk!1s
:  
1. 在FRED脚本编辑界面找到参考. u -;_y='m  
2. 找到Matlab Automation Server Type Library Q~OxH'>>(

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。 ->l%TCHP

现在将脚本代码公布如下，此脚本执行如下几个步骤： CS@FYO  
1. 创建Matlab服务器。 -&3hEv5  
2. 移动探测面对于前一聚焦面的位置。 mzeY%A<0^  
3. 在探测面追迹光线 ;LG#.~f  
4. 在探测面计算照度 /JHc!D  
5. 使用PutWorkspaceData发送照度数据到Matlab X'd9[).  
6. 使用PutFullMatrix发送标量场数据到Matlab中 "Q!(52_@J  
7. 用Matlab画出照度数据 `V`lo,"\  
8. 在Matlab计算照度平均值 m;'6MHx;  
9. 返回数据到FRED中 t; 4]cg:_
