/AW>5r] 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。
fNPj8\#V, S\5k'ifh 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:
0Zh
_Q enableservice('AutomationServer', true)
Y0\\(0j64 enableservice('AutomationServer')
Td1ba ^J
Sp,Q,Q4 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。
QCfpDE} pHB35=p28 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:
je4&'vyU 1. 在FRED脚本编辑界面找到参考.
f<:U"E. 2. 找到Matlab Automation Server Type Library
78CJ 3. 将名字改为MLAPP
Gc!8v}[7J -==qMrKP ,l .U^d6> 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。

0"psKf' 2. 移动探测面对于前一聚焦面的位置。
qmeml_(W 3. 在探测面追迹
光线 gQ=POJ=G 4. 在探测面计算
照度 36x:(-GFq 5. 使用PutWorkspaceData发送照度数据到Matlab
4)+IO; 6. 使用PutFullMatrix发送标量场数据到Matlab中
4t

#7-@k-<| 8. 在Matlab计算照度平均值
w<e;rKr 9. 返回数据到FRED中
