[分享]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。 {wS)M  
0^G5 zQlj  
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： fEgwQ-]  
enableservice('AutomationServer', true) 3mCf>qj73  
enableservice('AutomationServer') <5fb,@YN  
=
VFPZ  
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。 ] l@Mo7|w

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： dPx{9Y<FzU  
1. 在FRED脚本编辑界面找到参考. +T,Yf/^Fn  
2. 找到Matlab Automation Server Type Library Q"VS;uh.v  
3. 将名字改为MLAPP G Ch]5\

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。 y<0RgG1qp

现在将脚本代码公布如下，此脚本执行如下几个步骤： 8gK  <xp  
1. 创建Matlab服务器。 6_

2. 移动探测面对于前一聚焦面的位置。 ynQ+yW74Z  
3. 在探测面追迹光线 :IB@@5r1
 
4. 在探测面计算照度 R{R'byre  
5. 使用PutWorkspaceData发送照度数据到Matlab >dU.ic?19  
6. 使用PutFullMatrix发送标量场数据到Matlab中 #eZm)KFQg  
7. 用Matlab画出照度数据 7{f
Oo%(7  
8. 在Matlab计算照度平均值 -l2aAK1M  
9. 返回数据到FRED中  |tVWmm^m
