.Qt3!ek 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。
S=p u f'O vG@ 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:
YZRB4T9 enableservice('AutomationServer', true)
}yw;L(3 enableservice('AutomationServer')
+
nS/jW
~C/KA6H 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。
^gzNP#A<'o 1omvE9
%zM 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:
^4pKsO3ul 1. 在FRED脚本编辑界面找到参考.
7[BL 1HI* 2. 找到Matlab Automation Server Type Library
h)8+4?-4I 3. 将名字改为MLAPP
q-%KfZ@(| )V3(nZY ^~qs-.? 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。
