Z,/BPK<e 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。
8jW{0&ox) #W,BUN} 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:
}:C4T*| enableservice('AutomationServer', true)
2bBTd@m4 enableservice('AutomationServer')
Z.+-MN WV
WmTSxneo 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。
YXxaD@ ;u!qu$O 在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤:
4*W ??(=j 1. 在FRED脚本编辑界面找到参考.
0qXd?z$ 2. 找到Matlab Automation Server Type Library
<@xp. Y 3. 将名字改为MLAPP
u9rlNmf$ \tTZN 7ET^,6 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。

Q{6Bhx *> 1. 创建Matlab服务器。
P]:r'^Yn 2. 移动探测面对于前一聚焦面的位置。
<CIJg* 3. 在探测面追迹
光线 mw%do&e 4. 在探测面计算
照度 {aP5Mem 5. 使用PutWorkspaceData发送照度数据到Matlab
IBWUXG; 6. 使用PutFullMatrix发送标量场数据到Matlab中
P.mz$M 7. 用Matlab画出照度数据
,-^Grmr4M 8. 在Matlab计算照度平均值
o5KpiibFM 9. 返回数据到FRED中
