Hy~+|hLvh 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。
}nx5 2 ":W^P 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:
+Y!
P VMF enableservice('AutomationServer', true)
^ h?]$P enableservice('AutomationServer')
JYw_Z*L=m
ascY E 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。
eHl)/=' )45#lE3TH 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:
$a#-d; 1. 在FRED脚本编辑界面找到参考.
1DRih>+# 2. 找到Matlab Automation Server Type Library
e0:[,aF` 3. 将名字改为MLAPP
J\l'nqS" 5Y4#aq `i5 \(cdl 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。

HD_ #-M 1. 创建Matlab服务器。
`8lS)R! 2. 移动探测面对于前一聚焦面的位置。
H3>49;` 3. 在探测面追迹
光线 8= "01 4. 在探测面计算
照度 5HC5 5. 使用PutWorkspaceData发送照度数据到Matlab
RRUv_sff 6. 使用PutFullMatrix发送标量场数据到Matlab中
"&%Lhyt 7. 用Matlab画出照度数据
wTe 9OFv 8. 在Matlab计算照度平均值
ty\F~]Oo 9. 返回数据到FRED中
