[H$rdh[+ 简介:
FRED作为COM组件可以实现与Excel、VB、
Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。
^\Gaf5{ N|Mzj|i. 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令:
Q"n|<!DN enableservice('AutomationServer', true)
`j{5$X enableservice('AutomationServer')
L l\y2oJ
}DjW 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。
yyb8ll?@a 3QM6M9M 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:
JK34pm[s 1. 在FRED脚本编辑界面找到参考.
o Y{L0B[ 2. 找到Matlab Automation Server Type Library
^cB83%<Z 3. 将名字改为MLAPP
8%q:lI 8`l bKV \tH^w@j47 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。

y5gTd_- 3. 在探测面追迹
光线 +Q pgG4h 4. 在探测面计算
照度 1 ~fD: 5. 使用PutWorkspaceData发送照度数据到Matlab
%X)w$}WH 6. 使用PutFullMatrix发送标量场数据到Matlab中
