[技术]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。 n$oHr  
s}3`%?,6y  
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： QwSYjR:K  
enableservice('AutomationServer', true) Z.DO 2=+=  
enableservice('AutomationServer') BrO" _  
6*\WH%  
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。 exHg<18WSe

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： tr t^o  
1. 在FRED脚本编辑界面找到参考. rV0X*[]J>  
2. 找到Matlab Automation Server Type Library 5v`[c+@F  
3. 将名字改为MLAPP

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。 ^f%hhp

1. 创建Matlab服务器。 !

2. 移动探测面对于前一聚焦面的位置。 miTySY6^  
3. 在探测面追迹光线 c&GVIrJ  
4. 在探测面计算照度 1R+/T  
5. 使用PutWorkspaceData发送照度数据到Matlab ?;0w1  
6. 使用PutFullMatrix发送标量场数据到Matlab中 ^.HvuG},O  
7. 用Matlab画出照度数据 #{DX*;1
