zA9N<0[]o 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。
7xB#) o53 HnUM:-6 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:
kOETx enableservice('AutomationServer', true)
468LVe?0 enableservice('AutomationServer')
'IFbD["r
RPPxiYU^ 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。

wJ1qJ!s@ 1. 在FRED脚本编辑界面找到参考.
|;6FhDW+' 2. 找到Matlab Automation Server Type Library

R+P,kD? 4otB1{ *'`ByS 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。
