_sy{rnaqvb 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。
N+.Nu= +i2 3?E7\\/R 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:
wai3g-` enableservice('AutomationServer', true)
3nBZ+n4z enableservice('AutomationServer')
#GGa, @O EI=~*&t 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。
X!h>13fW jA"}\^%3 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:
ql9n`?Q 1. 在FRED脚本编辑界面找到参考.
POk5+^ 2. 找到Matlab Automation Server Type Library
Op0*tj2i), 3. 将名字改为MLAPP
xy`Y7W= /@
emE0 M?8sy 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。
