9Mwj:)} 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。
ptq{$Y{_ /~tfP 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令:
}>XSp)"{l enableservice('AutomationServer', true)
]R>k0X.V enableservice('AutomationServer')
j1iC1=`ZM
m<f{7]fi5 结果输出为1,这种操作方式保证了当前的Matlab实体可以用于
通信。
}EIwkz8 ;^8^L'7cr 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
# nYGKZ 1. 在FRED脚本编辑界面找到参考.
Y@\5gZ&T 2. 找到Matlab Automation Server Type Library
0j/81Y}p 3. 将名字改为MLAPP
?RzT0HRd Pd;ClMa% w+$gY?% 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。

z|?R=;,u` y?@Y\ b <d5vVn 现在将脚本代码公布如下,此脚本执行如下几个步骤:
4K;j:ZJ"x 1. 创建Matlab服务器。
l?1!h2z% 2. 移动探测面对于前一聚焦面的位置。
(MIw$)#^ 3. 在探测面追迹
光线 :d2u? +F 4. 在探测面计算
照度 XP^6*}H.* 5. 使用PutWorkspaceData发送照度数据到Matlab
"=n8PNV/
c 6. 使用PutFullMatrix发送标量场数据到Matlab中
9f6TFdUi"y 7. 用Matlab画出照度数据
omA*XXUx=8 8. 在Matlab计算照度平均值
0amz#VIB<u 9. 返回数据到FRED中
