YjoN:z`b 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。
)nTOIfP2 kce+aiv|u 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:
\c_1uDRoUn enableservice('AutomationServer', true)
Skq%S`1%Q enableservice('AutomationServer')
{pm>F}Cwy
+mYD
DlvI 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。
\<]nv}1O V<?t(_Y 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:
cdf8YN0!
1. 在FRED脚本编辑界面找到参考.
e:6R +8s2 2. 找到Matlab Automation Server Type Library
J$v0 3. 将名字改为MLAPP
BoHMz/DB Ik(TII_ 0r.*7aXu
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。

照度 ,ZC ^,Vq 5. 使用PutWorkspaceData发送照度数据到Matlab
AFF7fK 6. 使用PutFullMatrix发送标量场数据到Matlab中
