[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。 jyF*JQjK4  
G na%|tUz|  
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： 2DsP "q79k  
enableservice('AutomationServer', true) ><IWF#kUA  
enableservice('AutomationServer') /'.gZo  
2`;XcY4A  
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。 8Uh|V&

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[s+.&^  
1. 在FRED脚本编辑界面找到参考. E=,b;S-  
2. 找到Matlab Automation Server Type Library Hicd -'  
3. 将名字改为MLAPP @+zWLq!1pB

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。 Md>C!c

1. 创建Matlab服务器。 n2-+.9cY  
2. 移动探测面对于前一聚焦面的位置。 rxol7"2l
