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。 9^Fz iM 94skkEj 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: ~S,p?I enableservice('AutomationServer', true) b$%0.s enableservice('AutomationServer') t\P<X^d% ;V^pL((5J 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 c~QS9)=E hpTDxh'?$C 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: 40E#JF# 1. 在FRED脚本编辑界面找到参考. K~=UUB 2. 找到Matlab Automation Server Type Library 6 DG@?O 3. 将名字改为MLAPP 9O{b]=>wq fXI:Y8T Q+4tIrd+ 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。 _Z5Mw+=19 !q"W{P 图 编辑/参考 WE]e
