4kdQ h] 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。
kz?m `~1 1`l10f qU 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:
MP%pEUomev enableservice('AutomationServer', true)
2[TssJQ enableservice('AutomationServer')
$+Zj)V(
&+-]!^2o 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
c(!8L\69V} }q<%![% 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
#`b5kqQm 1. 在FRED脚本编辑界面找到参考.
2kQa3Pan 2. 找到Matlab Automation Server Type Library
q3$;lLsb;j 3. 将名字改为MLAPP
E|5lm @Sd l~'" b8TwV_&|X 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。
