[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。 ]LBvYjMY  
gJPDNZ*6pk  
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： 5+bFy.UW  
enableservice('AutomationServer', true) ?S@R~y0K  
enableservice('AutomationServer') S -
6"f/  
3 "l F  
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。 @0ov!9]Rw-

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： aXIB) $1  
1. 在FRED脚本编辑界面找到参考. >{ECyh;  
2. 找到Matlab Automation Server Type Library 'EL ||  
3. 将名字改为MLAPP "VDk1YX_&l

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。 L8:]`MQ0

1. 创建Matlab服务器。 mNx,L+3  
2. 移动探测面对于前一聚焦面的位置。 }0BL0N`_  
3. 在探测面追迹光线 Yz2{LW[K  
4. 在探测面计算照度 $v:gBlj%"  
5. 使用PutWorkspaceData发送照度数据到Matlab Mr=}B6`  
6. 使用PutFullMatrix发送标量场数据到Matlab中 #.)xm(Ys  
7. 用Matlab画出照度数据 :/@k5#DY  
8. 在Matlab计算照度平均值 n9kd2[s|  
9. 返回数据到FRED中 tg7C;rJ
