7Z<ba^r} 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。
wtw mN:p=.&
< 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:
r|tTDKGQ enableservice('AutomationServer', true)
iv/!c Mb enableservice('AutomationServer')
/Z*XKIU6v/
tk
<R|i
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。
"R/Xv+; Z>H
y+Q4 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:
kW@,P.88 1. 在FRED脚本编辑界面找到参考.
+MfdZD 2. 找到Matlab Automation Server Type Library
!4f0VQI 3. 将名字改为MLAPP
_ *O^|QbM g"iLhm`L A<VNttgG 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。
