ENs&RZ; 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。
5<Nx^D V {ddr:]4 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:
FWgpnI\X|{ enableservice('AutomationServer', true)
K1yzD6[eW enableservice('AutomationServer')
+VOK%8,p
-k e's 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。
>_ T-u<E )1`0PJoHE 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:
fJ!R6D 1. 在FRED脚本编辑界面找到参考.
}Oq5tC@$G 2. 找到Matlab Automation Server Type Library
r52gn(, 3. 将名字改为MLAPP
Pw"-S?`( Z,Dl` w I:1C8*/ 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。
