[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。 GGnlkp& E

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： ,jEc4ih4  
enableservice('AutomationServer', true) }
toe'6  
enableservice('AutomationServer') d)S`.Q  
&8w# 4*W  
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。 gyMHC{l/B

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： u7^(?"x  
1. 在FRED脚本编辑界面找到参考. ~|9VVeE  
2. 找到Matlab Automation Server Type Library I 1n,c d[  
3. 将名字改为MLAPP V y$*v

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。 iMt3h8

1. 创建Matlab服务器。 g0bYO!gCr  
2. 移动探测面对于前一聚焦面的位置。 =/_uk{  
3. 在探测面追迹光线 5wmd[YL  
4. 在探测面计算照度 y] c1x=x  
5. 使用PutWorkspaceData发送照度数据到Matlab Gc"

6. 使用PutFullMatrix发送标量场数据到Matlab中 u -P !2vT
