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。 kQd|qZ=:w [kxOv7a 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: j6k"%QHf enableservice('AutomationServer', true) f2M*]{N enableservice('AutomationServer') Dyo^O=0c xz.M'az\ 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。 6=,zkU*i^ lEHXh2 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: /|}yf/^9X 1. 在FRED脚本编辑界面找到参考. /~;!Ew|q 2. 找到Matlab Automation Server Type Library xw_)~Y%\ 3. 将名字改为MLAPP q`L)^In" o_k)x3I? b.?;I7r
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。 jgPUR#) i_r708ep6 图 编辑/参考 ]63!
