[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。 +o|I@7f  
tvcM< e20  
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： Mz: "p.  
enableservice('AutomationServer', true) >~*}9y0$  
enableservice('AutomationServer') dmPAPCm%y  
#n.XOet<\  
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。 GQ6~Si2

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： iC4rzgq  
1. 在FRED脚本编辑界面找到参考. Bmv5yc+;  
2. 找到Matlab Automation Server Type Library NeR1}W  
3. 将名字改为MLAPP @y8) "m"

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。 ,:xses*7

1. 创建Matlab服务器。 ^_t7{z%sA[  
2. 移动探测面对于前一聚焦面的位置。 B3W2?5p  
3. 在探测面追迹光线 2#X>^LH  
4. 在探测面计算照度 ?*:BgaR_  
5. 使用PutWorkspaceData发送照度数据到Matlab ^?S

6. 使用PutFullMatrix发送标量场数据到Matlab中 n!h952"  
7. 用Matlab画出照度数据 r#B{j$Rw   
8. 在Matlab计算照度平均值 u-R;rf5%k  
9. 返回数据到FRED中 ]SUW"5L-
