'_!j9A]g 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。
c]3% wL ^|-*amh 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:
-?{bCq enableservice('AutomationServer', true)
}+ ";W) R enableservice('AutomationServer')
j}}:&>;
)* 5R/oy, 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。
,[fn? s r NGZEUtj 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:
ti$d.Kc( 1. 在FRED脚本编辑界面找到参考.
0Yk@O)
x 2. 找到Matlab Automation Server Type Library
:KY920/, 3. 将名字改为MLAPP
ernZfd{H jzCSxuZ7O I{#&!h>]U 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 S

rz/^_dV 7. 用Matlab画出照度数据
&+F|v(|r 8. 在Matlab计算照度平均值
pdCn98}%- 9. 返回数据到FRED中
