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。 nD8CP[bRo h72#AN 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: #=* y7w enableservice('AutomationServer', true) (T]< enableservice('AutomationServer') |`50Tf\J mm,be. 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。 8^FAeV# n6f 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: a7Fc"s* 1. 在FRED脚本编辑界面找到参考. 9gLUM$Kd 2. 找到Matlab Automation Server Type Library uK5&HdoM 3. 将名字改为MLAPP z#!}4@_i3 2UF
,W] 5lc%GJybV 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。 *+wGXm wC~ra:/?:7 图 编辑/参考 :jc
