KSU?Tg&JR 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。
*jM~VTXwt %m$TV@ 配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令:
]`)50\pdw enableservice('AutomationServer', true)
^Lr)STh enableservice('AutomationServer')
(dn(:<_$
5 fY\0 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。
_Bm/v^( A@-nn] 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:
#D~atgR 1. 在FRED脚本编辑界面找到参考.
@ de_|*c 2. 找到Matlab Automation Server Type Library
d%VG@./xq 3. 将名字改为MLAPP
|3`Sd;^; #ak2[UOT :fz&)e9 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。

IH8^ fyQ` 1. 创建Matlab服务器。
%>Z;/j|#r 2. 移动探测面对于前一聚焦面的位置。

光线 Hv2t_QjKT 4. 在探测面计算
照度 OEmz`JJ67 5. 使用PutWorkspaceData发送照度数据到Matlab
"Opk:;. 6. 使用PutFullMatrix发送标量场数据到Matlab中
gjB36R 7. 用Matlab画出照度数据
