{npm9w<; 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。
#U:|-
a.> v[dUUR f 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:
{ 'b;lA]0 enableservice('AutomationServer', true)
!"^Zr]Qt+\ enableservice('AutomationServer')
Y'U1=w~E
q
G%Y & P 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。

yE}\4_0I/ 1. 在FRED脚本编辑界面找到参考.
a?[[F{X9^ 2. 找到Matlab Automation Server Type Library

xHK 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。
