$M Jm*6h 简介:
FRED作为COM组件可以实现与Excel、VB、
Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。
mc4i@<_? rx}r~0i 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令:
tJN<PCG6" enableservice('AutomationServer', true)
.9.2Be enableservice('AutomationServer')
W%\C_
av~5l4YL 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
5xL~`-IA&v }NB}"%2 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
f5 `g 1. 在FRED脚本编辑界面找到参考.
K$d$m < 2. 找到Matlab Automation Server Type Library
n0is\ZK 0 3. 将名字改为MLAPP
X]y)qV)a[c bJD;>"* 8g7<KKw 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 7x<i :x3 4. 在探测面计算
照度 P~ &$l2 5. 使用PutWorkspaceData发送照度数据到Matlab

n93=8;& 7. 用Matlab画出照度数据
k?7 X3/O 8. 在Matlab计算照度平均值
+zs4a96[ 9. 返回数据到FRED中
