[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。 -

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： oz=ULPZ%  
enableservice('AutomationServer', true) _dk[k@5W{'  
enableservice('AutomationServer') *Ts$Hj[  
Ff/Ap&0+  
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。 Posz|u<x

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<V1`e  
1. 在FRED脚本编辑界面找到参考. 6?M/71
 
2. 找到Matlab Automation Server Type Library nD eVYK  
3. 将名字改为MLAPP EL3X8H

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。 +jB;

1. 创建Matlab服务器。 ^\B4]'+^j

6. 使用PutFullMatrix发送标量场数据到Matlab中 -( p%+`  
7. 用Matlab画出照度数据 3^ UoK  
8. 在Matlab计算照度平均值 tTTHQ7o*BD
