[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。 l|5ss{llR  
;QW)tv.y  
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： ^\Jg {9a  
enableservice('AutomationServer', true) b:W]L3Z8  
enableservice('AutomationServer') <q
v:7@  
cBc6*%ZD  
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。 ~Dgui/r9J

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： bzB9u&  
1. 在FRED脚本编辑界面找到参考. =p^*y-z  
2. 找到Matlab Automation Server Type Library >W 8!YOc  
3. 将名字改为MLAPP 1xcx2L+R

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。 Rp9uUJ 6o

5. 使用PutWorkspaceData发送照度数据到Matlab SE%i@}  
6. 使用PutFullMatrix发送标量场数据到Matlab中 h`Y t4-Y  
7. 用Matlab画出照度数据 7|"11^q
