[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。 "TgE@bC  
Q]]5\C.  
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： u/8urxpy  
enableservice('AutomationServer', true) u/2!v
(  
enableservice('AutomationServer') {Z=m5Dy}  
fsDwfwil*  
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。 l[J'FR:

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： h&4f9HhS=  
1. 在FRED脚本编辑界面找到参考. )|@ H#kv?  
2. 找到Matlab Automation Server Type Library *1[v08?!  
3. 将名字改为MLAPP P5*~Wi`

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。 &4ScwK:
