2N~ E' 25 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。
}t>q9bZ9z (\dK4JJ 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:
ACV ek enableservice('AutomationServer', true)
qd!#t] enableservice('AutomationServer')
?A7Yk4Y.?N
6U,fz#<,} 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。
y~F<9;$= ,vG<*|pn 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:

vN{-?
3. 将名字改为MLAPP
C%ytkzG_ ~4)Y#IxL i~& c| 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。
