yM17H\ = 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。
>nNl^ yqW ~h|m&XK+Q 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:
Xoi9d1fO enableservice('AutomationServer', true)
X!7Xg enableservice('AutomationServer')
{e6KJ@H6
@ay|]w 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]^Xm3{@ iE+6UK 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:
4g'}h`kh 1. 在FRED脚本编辑界面找到参考.
]j1
vbk 2. 找到Matlab Automation Server Type Library
UFk!dK+ 3. 将名字改为MLAPP
p\ok_*b JP_kQ M/)B" q 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。

l }+Cdy9> 3. 在探测面追迹
光线 64b<0;~ 4. 在探测面计算
照度 mOSCkp{<e 5. 使用PutWorkspaceData发送照度数据到Matlab
