[&nh5|f 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。
<_XWWT% 'ul~7h;n 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:
-$WYj" enableservice('AutomationServer', true)
Nqrmp" ] enableservice('AutomationServer')
x
>^Si/t
5<ux6,E1{ 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
H8`(O"V Hv\-_>}K 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
d\ ~QBr? 1. 在FRED脚本编辑界面找到参考.
W~p/,H cM 2. 找到Matlab Automation Server Type Library
k}0^&Quc4 3. 将名字改为MLAPP
&bp=`=* NN1$'"@NL 2w-51tqm 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。

照度 C,pJ`:P 5. 使用PutWorkspaceData发送照度数据到Matlab
-atGlu2 6. 使用PutFullMatrix发送标量场数据到Matlab中
&2=dNREJ}1 7. 用Matlab画出照度数据
@;H,gEH^ 8. 在Matlab计算照度平均值
OKvPL=~ 9. 返回数据到FRED中
