[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。 zj|/ CxV  
=U. b% uC  
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： 7DfTfTU6  
enableservice('AutomationServer', true) 2F8|I7R  
enableservice('AutomationServer')  6st^4S5  
L@^~N$G&u  
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。 f):~8_0b

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： <q,+ON\'  
1. 在FRED脚本编辑界面找到参考. SjEdyN#  
2. 找到Matlab Automation Server Type Library 8:.nEo'  
3. 将名字改为MLAPP M- 0i7%

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。 Fn^C{p^

4. 在探测面计算照度 g8'DoHJ*  
5. 使用PutWorkspaceData发送照度数据到Matlab jFerYv&K~  
6. 使用PutFullMatrix发送标量场数据到Matlab中 m/`IGT5J  
7. 用Matlab画出照度数据 Be}$I_95\P
