[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。 C)^FRnb

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： .Z=4,m
>  
enableservice('AutomationServer', true) EJqzh
i5  
enableservice('AutomationServer') )9_jr(s  
oicett=5  
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。 -9BKa~ DVQ

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： %(4G[R[  
1. 在FRED脚本编辑界面找到参考. }gw `,i  
2. 找到Matlab Automation Server Type Library e@k`C{{C]o  
3. 将名字改为MLAPP qX'w}nJ}H}

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。 D;bQ"P-m47

4. 在探测面计算照度 ld1t1'I'  
5. 使用PutWorkspaceData发送照度数据到Matlab E-,74B&H
