`(+o=HsD 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。
B&+`)E{KB /iNa'W5\ 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:
Qp"y?S enableservice('AutomationServer', true)
f %lD08Sl enableservice('AutomationServer')
EpS(o>'
p^nL&yIW,% 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。
_Y=2/*y^ m=AqV:%| 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:
t>GfM 1. 在FRED脚本编辑界面找到参考.
(BxJryXm 2. 找到Matlab Automation Server Type Library
UX3BeUi.) 3. 将名字改为MLAPP
.x`M<L#M( n%R;-?*v $WYbm}j 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 9YsR~SM 5. 使用PutWorkspaceData发送照度数据到Matlab
Rj F'x 6. 使用PutFullMatrix发送标量场数据到Matlab中
ONNpiK- 7. 用Matlab画出照度数据
di)*-+ 8. 在Matlab计算照度平均值
B/5=]R 9. 返回数据到FRED中
