[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。 )|Ka'\x

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： FJW,G20L  
enableservice('AutomationServer', true) #210 Yp#  
enableservice('AutomationServer') }L^PZS@Jf  
G12o?N0p  
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。 OY!WEP$F-C

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： "VMb1Zhf  
1. 在FRED脚本编辑界面找到参考. 0rAuK7  
2. 找到Matlab Automation Server Type Library >aCY  
3. 将名字改为MLAPP LftGA7uGJ)

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。 iU#"G" &

现在将脚本代码公布如下，此脚本执行如下几个步骤： un)PW&~E  
1. 创建Matlab服务器。 t^~itlE{  
2. 移动探测面对于前一聚焦面的位置。 J@ 8OU  
3. 在探测面追迹光线 J d,9<m$  
4. 在探测面计算照度 t\n'Kuk`  
5. 使用PutWorkspaceData发送照度数据到Matlab ?H8dyQ5"  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ?MvL}o\|  
7. 用Matlab画出照度数据 jk%H+<FU`  
8. 在Matlab计算照度平均值 X0LC:0+  
9. 返回数据到FRED中 q3
