[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。 P/;d|M(  
+ht{ARX2(  
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： P8=!/L2?  
enableservice('AutomationServer', true) VMb r@9  
enableservice('AutomationServer') OjRJyhzS*  
WC *e#QP  
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。 +ew9%={zB

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： xIb^x=|h  
1. 在FRED脚本编辑界面找到参考. f_qW+fN::s  
2. 找到Matlab Automation Server Type Library QGM@m:O  
3. 将名字改为MLAPP )[d>?%vfd

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。 WZ]f \S

2. 移动探测面对于前一聚焦面的位置。 8O_0x)X  
3. 在探测面追迹光线 6x8P}?  
4. 在探测面计算照度 M9scZuj  
5. 使用PutWorkspaceData发送照度数据到Matlab !=yNj6_f  
6. 使用PutFullMatrix发送标量场数据到Matlab中 mpysnKH  
7. 用Matlab画出照度数据 TqN4OkCm/  
8. 在Matlab计算照度平均值 ()+PP}:$A  
9. 返回数据到FRED中 \n`)>-
