y<HNAGj 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。
w3VgGc~ *oLDy1< 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:
x4 4V
9-o enableservice('AutomationServer', true)
3
[#Rm>,Vu enableservice('AutomationServer')
}T PyHq"
EhKG"Lb+ 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。
xVYa-I[Z 4C?4M; 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:
GwA\>qXw 1. 在FRED脚本编辑界面找到参考.
#I MaN% 2. 找到Matlab Automation Server Type Library
: &nF> 3. 将名字改为MLAPP
|Ch,C amExZ/ 3_9CREZCl 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。

O46v ;,uATd| {2Ew^Li 现在将脚本代码公布如下,此脚本执行如下几个步骤:
-Ju;i< 1. 创建Matlab服务器。
+BO kHXk1 2. 移动探测面对于前一聚焦面的位置。
`t9k!y!GV 3. 在探测面追迹
光线 hwvi tD!0 4. 在探测面计算
照度 S~H>MtX(< 5. 使用PutWorkspaceData发送照度数据到Matlab
y8C8~ -&OK 6. 使用PutFullMatrix发送标量场数据到Matlab中
86cnEj= 7. 用Matlab画出照度数据
QrFKjmD< 8. 在Matlab计算照度平均值
#Muh|P]%\ 9. 返回数据到FRED中
