e&&;"^@- 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。
3/sKRU e_C9VNP 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:
F\m
enableservice('AutomationServer', true)
y'sy]Q~ enableservice('AutomationServer')
-9BKa~ DVQ
KM$5ZbCF: 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。
o`^GUY} 1_JxDT,=> 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:
\Ol3kx| 1. 在FRED脚本编辑界面找到参考.
tT7< V{i4 2. 找到Matlab Automation Server Type Library
gI^);JrTE 3. 将名字改为MLAPP
y w"Tw n^QOGT.s6` +3VDapfin 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 6T6 S9A*nT 5. 使用PutWorkspaceData发送照度数据到Matlab
AYHfe#! 6. 使用PutFullMatrix发送标量场数据到Matlab中
