)S3\,S-. 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。
toLV4BtIG t9nqu!); 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:
A_V]yP enableservice('AutomationServer', true)
G, 44va enableservice('AutomationServer')
,aOl_o -&
'SO %)B 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。
Moy <@+ ?U%QG5/> 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:
^/)^7\@ 1. 在FRED脚本编辑界面找到参考.
2$9odD<r 2. 找到Matlab Automation Server Type Library
()2I# 3. 将名字改为MLAPP
^"2i tI]Q%S, Jlri*q"hE 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。

光线 vV6<^W:9F 4. 在探测面计算
照度 4Fa~Aog 5. 使用PutWorkspaceData发送照度数据到Matlab

B+Rm>^CBm 8. 在Matlab计算照度平均值
