e W*nRha 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。
45`Gv '{EBK 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:
X~RET[L2 enableservice('AutomationServer', true)
\$J!B&i enableservice('AutomationServer')
Kb%j;y
bA#E8dlC_ 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。
g<~[k?~J !ViHC}: 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:
3"'|Ql.H 1. 在FRED脚本编辑界面找到参考.
U[~BW[[@f 2. 找到Matlab Automation Server Type Library
di6A.N5A 3. 将名字改为MLAPP
Z2B59,I (mHFyEG 2vKnxK+ 5 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 Ks09F} 4. 在探测面计算
照度
K)GC&%_$O 5. 使用PutWorkspaceData发送照度数据到Matlab

O*oL(dk*8L 7. 用Matlab画出照度数据
eU7RO 8. 在Matlab计算照度平均值
'dj}- Rs 9. 返回数据到FRED中
