O.#Rr/+) 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。
A'![*O qPi $kecx 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-^*p enableservice('AutomationServer', true)
"r;cH5 3 enableservice('AutomationServer')
%;]/Z%!
D]d! lMK/ 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。
^{J^oZ'%~ E\Wd*,/v) 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:
vR#MUKfh 1. 在FRED脚本编辑界面找到参考.
A"DGn 2. 找到Matlab Automation Server Type Library
rp
@%0/[ 3. 将名字改为MLAPP
5Th\wTh04 G~_eBy IecD41% 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。

b+RU <qR 3. 在探测面追迹
光线 MP@}G$O 4. 在探测面计算
照度 UC`sq-n 5. 使用PutWorkspaceData发送照度数据到Matlab
B~Z61 6. 使用PutFullMatrix发送标量场数据到Matlab中
5y='1s[% 7. 用Matlab画出照度数据
