[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。 !;>j(xc  
G[GSt`LVS`  
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： [WW3'= e^  
enableservice('AutomationServer', true) sk6C/ '0:  
enableservice('AutomationServer') f!AcBfaLr  
{94qsVxQZ  
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。 [jU.58*

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： ,ir(~g+{g  
1. 在FRED脚本编辑界面找到参考. F$X"?fj  
2. 找到Matlab Automation Server Type Library 1%g%I8W%  
3. 将名字改为MLAPP K 0R<a~

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。 Fu].%`*xJ

现在将脚本代码公布如下，此脚本执行如下几个步骤： <A"[Wk  
1. 创建Matlab服务器。 "k&QS@l  
2. 移动探测面对于前一聚焦面的位置。 m`_

3. 在探测面追迹光线 j6}/pe*;;T  
4. 在探测面计算照度 A0JlQE&U  
5. 使用PutWorkspaceData发送照度数据到Matlab dz_~_|  
6. 使用PutFullMatrix发送标量场数据到Matlab中 u)J&3Ah%  
7. 用Matlab画出照度数据 W~b->F  
8. 在Matlab计算照度平均值 kbu.KU+  
9. 返回数据到FRED中 6_}& WjU'
