[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。 (Dw,DY9  
F({HP)9b  
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： {[+mpKq
 
enableservice('AutomationServer', true) KVT-P};jy*  
enableservice('AutomationServer') {@+Ty]e  

~io szX  
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。 7* yzEM

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： `8AR_7i  
1. 在FRED脚本编辑界面找到参考. X$ s:>[H  
2. 找到Matlab Automation Server Type Library }s(N6a&(  
3. 将名字改为MLAPP 0w)^)

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。 U.DDaT1
